Frequently asked questions
Cannot find what you need? Get in touch .
Are the tools really free?
Yes. Every tool on this site is free to use — no account, no subscription, no card details. Advertising covers the running costs.
Do my files get uploaded to a server?
No. Conversion, editing and calculation all happen inside your browser, using WebAssembly and the codecs your browser already ships with. Your file never leaves your device, so we cannot see it either.
What file types can I work with?
Images (JPG, PNG, WebP, AVIF, HEIC, TIFF, SVG), animation (GIF, APNG, animated WebP), video and audio through an in-browser FFmpeg build, PDF documents, and spreadsheets in CSV or XLSX form.
Is there a file size or batch limit?
There is no artificial limit. Batches of fifty images, or spreadsheets with tens of thousands of rows, run in a background worker so the page stays responsive; how long it takes depends on your own machine.
Can I use the output commercially?
Yes. The files you produce are yours. We claim no rights over anything you convert, and nothing is stored, logged or reused.
