Where FileToolWorks Wins
FileToolWorks processes everything in your browser. Your files never get uploaded anywhere. This means no file size caps, no daily conversion limits, and no waiting for server processing. If you work with sensitive documents or large media files, this matters.
There is no account to create and nothing to pay for. You open the tool, drop your file in, and get your result. The audio compressor, PDF merger, and video to GIF converter are the most popular tools.
Where Convertio Wins
Convertio supports over 300 file formats, including niche types like CAD files and ebook formats that FileToolWorks does not cover. Server-side processing can be faster for very large video files since the work happens on their hardware, not your browser.
If you need to convert between obscure formats (like DWG to SVG or EPUB to MOBI), Convertio has broader coverage.
Who Should Use FileToolWorks
Pick FileToolWorks if you want unlimited free conversions with zero friction. It covers the formats most people actually need: images (PNG to JPG, Image to WebP), PDFs (compress, sign, extract pages), video (compress, convert to MP4), and audio (compress, WAV to MP3).
Frequently Asked Questions
Is FileToolWorks really free?
Yes. Every tool is free with no daily limits, no file size caps, and no paid tiers. There is nothing to upgrade to.
Why does FileToolWorks have no file size limit?
Because processing happens in your browser using WebAssembly. Files never leave your device, so there are no server costs to limit.
Does Convertio store my files?
Convertio uploads files to their servers for processing and deletes them after 24 hours. FileToolWorks never uploads your files at all.
Which has more formats?
Convertio supports more niche formats (300+). FileToolWorks covers the 40+ most common conversion tasks that handle 95% of use cases.
Do I need to install anything?
Neither requires installation. Both work entirely in your web browser.
Which is faster?
For typical files, FileToolWorks is faster because there is no upload step. For very large video files, Convertio's servers may process faster than your local browser.
