Frequently Asked Questions

Everything you need to know about Imageconvertix.

Yes, Imageconvertix is 100% free for the basic plan. All core features including image compression, format conversion, and batch processing up to 10 files are available without any sign-up or hidden fees. We also offer Pro ($100/mo) and Enterprise ($150/mo) plans for advanced features.
No. All file processing happens entirely in your browser using JavaScript and WebAssembly. Your images and documents never leave your device. There is no server upload, no temporary storage, and no third-party access.
Imageconvertix supports JPEG, PNG, WebP, AVIF, BMP, and TIFF for compression and conversion. We also support document formats like Excel (.xlsx), Word (.docx), HTML, and CSV for PDF conversion.
The free plan supports up to 10 files per batch. The Pro plan supports up to 100 files, and the Enterprise plan offers unlimited batch processing. All files are processed simultaneously for maximum speed.
Imageconvertix uses intelligent compression algorithms that minimize visible quality loss. At the default 80% quality setting, most images are 60-80% smaller with virtually no visible difference. You can fine-tune the quality slider from 1-100 or set a target file size.
Yes! After the initial page load, Imageconvertix works fully offline. Since all processing happens in your browser, you don't need an internet connection. Perfect for working on the go.
Target file size mode lets you specify exactly how large you want the output file to be (e.g., 500KB). Imageconvertix automatically adjusts compression quality to hit your target as closely as possible. Ideal for email attachments or CMS upload limits.
Absolutely. Imageconvertix is fully responsive and works on any device with a modern web browser including smartphones, tablets, laptops, and desktops.
Lossy compression (JPEG, WebP) permanently removes less-important visual data to achieve dramatically smaller files. Lossless compression (PNG) reduces file size without any data loss. For web use, lossy compression at 75-85% quality offers the best balance of size and quality.
Simply drag and drop your .xlsx file into the Imageconvertix document converter on the home page. The tool automatically detects the format and converts it to a professionally formatted PDF. Everything happens in your browser, keeping your data private.
Never. Imageconvertix does not add any watermarks, logos, or branding to your compressed or converted files. The output files are clean and ready to use, on every plan including the free tier.
Imageconvertix works on all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. We recommend using the latest version for optimal performance, especially when processing large batches.

Everything You Need to Know About Imageconvertix

Imageconvertix is a free, browser-based file processing platform that lets you compress images, convert image formats, and transform documents without installing any software and without uploading your files to a remote server. Every tool on this platform runs entirely inside your web browser using modern JavaScript APIs, which means your files stay private, your data stays on your device, and results are delivered in seconds rather than waiting for a server queue.

How Does Browser-Based Compression Work?

When you drop an image into Imageconvertix, the browser reads it using the File API, decodes the pixel data onto an HTML Canvas, re-encodes it at your chosen quality setting, and hands you back a download link, all without a single byte of your file travelling over the internet. This approach is made possible by the Canvas API's built-in JPEG, PNG, WebP, and AVIF encoders that ship in every modern browser. For more advanced formats like HEIC, TIFF, PSD, TGA, and PPM, Imageconvertix loads dedicated pure-JavaScript decoder libraries that run locally, so even these formats are handled entirely on-device.

Which Image Formats Does Imageconvertix Convert?

Imageconvertix supports over 40 image formats for conversion. Common formats include JPEG, PNG, WebP, AVIF, GIF, BMP, ICO, and TIFF. Professional and specialty formats include PSD, PSB, EPS, PS, TGA, PPM, PGM, PNM, JFIF, and XCF. Camera RAW formats supported include ARW, CR2, CR3, CRW, DCR, DNG, ERF, MOS, MRW, NEF, ORF, PEF, RAF, RAW, RW2, and X3F. Mobile formats such as HEIC and HEIF are also fully supported. Each format has a dedicated conversion page with explanations of what the format is, when to use it, and how to convert it for free without any upload.

Is Imageconvertix Safe for Sensitive Files?

Yes. Because Imageconvertix processes files entirely in your browser, it is one of the safest online tools available for handling sensitive content. Confidential business documents, personal photographs, proprietary design files, and medical images can all be processed with zero risk of exposure to third parties. No files are stored, no analytics tools track file contents, and no employee of Imageconvertix has any technical ability to see what you are processing. This design makes Imageconvertix fully compatible with GDPR requirements and suitable for use in regulated industries.

What Document Conversions Are Available?

Beyond image tools, Imageconvertix provides a comprehensive document conversion suite. You can convert Word (.docx) to PDF, Excel (.xlsx) to PDF, HTML to PDF, CSV to JSON, JSON to CSV, Markdown to HTML, PDF to Word, and PDF to Excel. All document conversions also run locally in your browser using libraries such as mammoth.js for Word processing, SheetJS for Excel, and PDF.js for PDF parsing. This means no Microsoft Office installation is required and no files are sent anywhere.

Why Choose Imageconvertix Over Other Online Tools?

Most online file converters and compressors upload your files to their servers, process them remotely, and then serve a download link. This creates privacy risks, introduces latency, and often comes with file size caps or rate limits. Imageconvertix eliminates all of these drawbacks by keeping everything local. There are no file size limits imposed by server capacity, no wait times caused by upload queues, no watermarks added to your output, and no accounts required. The result is a tool that is faster, more private, and simpler to use than any server-dependent alternative.
