About This Tool

Built for Speed, Privacy and Precision

A single tool that handles image compression, format conversion, and document processing, all without leaving your browser.

What Is Imageconvertix?

Imageconvertix is a free online image compressor and file converter that works entirely inside your browser. You do not need to upload anything to a server, create an account, or install software. Every single operation happens locally on your own device, which means your photos and documents stay completely private from start to finish.

Whether you need to reduce image file size for a website, compress photos for email, or convert PNG to JPG for a client, Imageconvertix gets it done in seconds. The tool supports more than 50 file formats and handles batch processing of up to 50 files at once, making it just as useful for professional designers and developers as it is for everyday users who just want to shrink a photo before sending it.

There are no file size limits, no watermarks, no subscriptions, and no annoying pop-ups asking you to upgrade. It is genuinely free, and it always will be.

Intelligent Image Compression

Imageconvertix analyses each image individually to find the right balance between file size and visual quality. You can reduce photos by up to 90% while keeping them looking nearly identical to the original. Use preset target sizes such as 100 KB, 200 KB, or 1 MB, or dial in quality manually with the precision slider. The compressor supports JPEG, PNG, WebP, and AVIF images and processes everything right inside your browser.

Support for 50+ File Formats

One of the things people appreciate most about Imageconvertix is how many formats it handles. You can convert between JPEG, PNG, WebP, AVIF, BMP, GIF, HEIC, TIFF, ICO, PSD, EPS, SVG, and many more. The converter also handles batch jobs of up to 50 files at once, so whether you are doing a quick one-off conversion or processing an entire folder of assets, the tool handles it with ease.

Why Compress Images Online?

If you have ever wondered why your website loads slowly or why your email bounces because the attachment is too large, oversized images are usually the culprit. Large image files slow down page load times, hurt your Core Web Vitals scores, and push users away before your content even appears. Compressing images online is one of the easiest and most effective ways to fix that.

With a free image compressor like Imageconvertix, you can reduce image file size dramatically without any visible loss in quality. A 3 MB photo can become 300 KB or less. A folder of product images that would have taken seconds to load can be cut down to something that feels instant. And since all of this happens in your browser, there is no waiting for uploads or dealing with slow server processing.

This matters whether you are a web developer optimizing a client site, a blogger uploading photos, a freelancer sharing mockups, or just someone who wants to send a batch of vacation photos without hitting attachment limits.

Fully Private by Design

Every operation runs directly inside your browser using WebAssembly and the Canvas API. Nothing is ever transmitted to any server at any point. Your files stay on your device from start to finish, which makes it a genuinely safe choice for confidential documents, client assets, and personal photos. Zero files uploaded to any server, guaranteed.

Document Conversion Built In

Go beyond images. Convert Excel spreadsheets and Word documents to PDF, convert HTML pages to PDF, or transform CSV data to JSON and back, all within the same tool. No cloud service, no account, no file size ceiling. Just open the Document Converter tab and drop your file. It is really that simple.

Convert PNG to JPG, WebP, AVIF and More

Image format conversion is something almost everyone needs at some point. Maybe you have a PNG file but your platform requires JPG. Maybe you want to switch to WebP to improve your website performance. Or maybe you have received HEIC photos from an iPhone and need to convert them to a more universal format like JPEG or PNG.

Imageconvertix makes all of these conversions simple. Click the Image Converter tab, choose your target format from the grid, and drop your files in. The conversion happens instantly, with no quality loss and no server uploads. You can convert PNG to JPG, JPG to WebP, WebP to PNG, AVIF to JPG, HEIC to JPG, BMP to JPG, and many other combinations with a few clicks.

If you want the best results for web use, consider converting your images to WebP or AVIF. WebP files are typically 25 to 35% smaller than JPEG at the same visual quality, and AVIF can be even more compact. Both formats are well supported by modern browsers and can make a noticeable difference to your page speed scores.

Batch Image Processing

You do not have to process images one at a time. Drop up to 50 files at once into the compressor or converter and they will all be processed simultaneously. Once done, you can download each file individually or grab the entire batch as a ZIP archive with a single click. This makes Imageconvertix a practical choice for agencies, photographers, and ecommerce teams who deal with large volumes of images on a regular basis.

Works on Any Device

Imageconvertix is fully responsive and works on desktop, tablet, and mobile. Whether you are on a Windows PC, a Mac, an Android phone, or an iPhone, you will get the same smooth, fast experience in any modern browser. There is nothing to install and nothing to configure. Open the site, drop your files, and you are done.

How to Reduce Image File Size Online for Free

Getting started with Imageconvertix takes less than a minute. Here is how it works:

  1. Choose a target size or quality level. Use the preset size chips (5 KB to 5 MB) for precise control, or leave them blank and use the quality slider to set your preferred compression level manually.
  2. Drop your images into the Compressor tab. You can drag and drop files directly from your desktop or click to browse and select them. JPEG, PNG, WebP, and AVIF are all supported.
  3. Download your compressed images. Each file appears in the results panel with a before-and-after size comparison. Download them individually or click "Download All" to grab everything as a ZIP.

That is genuinely all there is to it. No loading screens, no server queues, no waiting. The whole process typically takes just a few seconds even for large batches, because everything runs locally in your browser without ever touching a server.

Free Image Converter for Web Developers and Designers

If you build websites or work with digital assets professionally, Imageconvertix fits neatly into your workflow. Converting a library of PNG screenshots to WebP before pushing a site live takes just a couple of minutes. Compressing product images for an ecommerce store before upload saves storage and speeds up page load. Converting client-provided HEIC photos from iPhones to JPEG for use in design tools is a one-click job.

The document converter is equally useful. Instead of needing a separate tool for Excel to PDF or Word to PDF conversions, you can do it all here, right inside the browser, without sending files to any third-party service. The CSV to JSON and JSON to CSV converters are handy for developers working with data pipelines who need a quick format switch without writing a script.

Because all processing is local, you can use Imageconvertix confidently with sensitive files, client work, and anything that should not leave your machine. It is one of those tools that just makes sense to keep open in a browser tab.

To convert and compress an image to JPG at exactly 20KB, use the Compressor tab on Imageconvertix. Click the 20kb size chip above the drop zone, then drop your image. The tool will automatically compress it to fit within 20KB while keeping the best possible quality. If you need a specific output size like 20KB, this target-size feature gives you precise control without any guesswork.
Click the 100kb chip in the Compressor tab, then drop your image. Imageconvertix will reduce the file to 100KB or under while preserving as much visual quality as possible. This is ideal for online forms, job applications, and platforms that enforce a 100KB file size limit on uploaded photos.
Select the 50kb chip in the Compressor tab and drop your image. The tool compresses it to fit within 50KB automatically. This is commonly needed for government portals, college admission forms, and official document upload systems that require a very small passport-sized photo.
Use the 200kb size chip in the Compressor tab to compress your image to 200KB or less. Drop your JPG, PNG, or WebP file and the tool handles the rest. A 200KB target is a common requirement for profile photos, application photos, and website thumbnails where you want good quality without a heavy file.
For a 30KB output, use the Custom size chip in the Compressor tab and type in 30. The compressor will reduce your image to that exact target size. Very small sizes like 30KB are often required for scanned document thumbnails or specific government ID portals with strict upload limits.
Click the 2mb chip in the Compressor tab and drop your image. The tool will compress it to fit within 2MB. This is useful when you have a very large raw file or a high-resolution photo and need to reduce it to under 2MB for email attachments, social media uploads, or e-commerce product listings.
Open the Image Converter tab, click the JPG format button, and drop your PNG file. The PNG to JPG conversion happens in seconds with no quality loss. You can also convert in bulk by dropping multiple PNG files at once. Visit our dedicated PNG Converter page for additional options.
HEIC is the default photo format on iPhones. To convert HEIC to JPG, open the Image Converter tab, select JPG as the output format, and drop your HEIC file. The conversion is instant and free. This is especially handy if you are sharing iPhone photos with people or platforms that do not support the HEIC format. You can also visit our HEIC Converter page.
Open the Image Converter tab, click JPG, and drop your WebP file. The conversion is instant and completely free. WebP to JPG conversion is useful when you have downloaded images from a website and need them in a format that works with older software, email clients, or image editors. Visit our WebP Converter page for more options.
JPEG and JPG are the same format. The only difference is the file extension. If you have a .jpeg file and need a .jpg file, simply use the Image Converter tab, select JPG, and drop your file. You can also just rename the file extension from .jpeg to .jpg on your device and it will work identically.
Use the Custom size chip in the Compressor tab and enter 90 as the target. Imageconvertix will compress your image to 90KB or under automatically. This works for JPEG, PNG, WebP, and AVIF images. The tool adjusts the quality level intelligently so the image looks as good as possible at your chosen size.
Click the 100kb chip in the Compressor tab and drop your image. The tool automatically reduces the file size to 100KB or less while keeping quality as high as possible. A 100KB limit is common for profile photos on job portals, college application forms, and business registration sites.
Select the 20kb size chip in the Compressor tab and drop your image. The tool will compress it to 20KB or below. This very small file size is typically required for thumbnails, government portals like exam application portals, and official document submission systems that enforce strict upload size limits.
Click the 200kb chip in the Compressor tab, then drop your JPEG, PNG, or WebP image. Imageconvertix compresses it to fit within 200KB automatically. This is a common requirement for social media profile pictures, business portal uploads, and document submission forms where good image quality is still important.
To reduce an image to 50KB in file size, use the 50kb size chip in the Compressor tab. Imageconvertix reduces the file size by adjusting image quality rather than changing the pixel dimensions. This gives you a smaller file while keeping the same width and height. If you need to change actual pixel dimensions, use the quality slider to reduce quality and pair it with a target size chip.
Use the 200kb target chip in the Compressor tab to reduce your image file size to 200KB or below. This is the easiest way to resize an image for file size without any technical knowledge. Drop your file, click the chip, and download your resized image. It works on JPEG, PNG, WebP, and AVIF files.

Your photo will be converted to JPG instantly and you can save it to your phone, then share it on WhatsApp. Converting to JPG also helps keep the file small enough to send without WhatsApp compressing it further.
iPhones save photos as HEIC by default, which many apps and platforms do not support.

The conversion happens instantly and you can save the JPG directly back to your iPhone photos.
