Frequently Asked Questions
More on quality loss: conversion quality guides · compression guides
Is this tool free?
Yes. Format Convertly tools run free in your browser with no signup required.
Do you store my files?
No. Processing stays on your device — there is no tool upload to our servers.
Does it work on mobile?

Need a format conversion instead?
Open the converters catalog for JPG, PNG, PDF, MP4, and hundreds of other pairs.
Does compressing or converting images reduce quality?
Lossy compression can. Use higher quality settings when fidelity matters, and keep an original master. Lossless workflows preserve pixels.
Can you recover quality after compressing?
Not from the compressed file alone. Keep the original upload/export and recompress from that master if you need a better result.
What is generational loss?
Quality damage from repeatedly re-encoding lossy images. Avoid save→compress→save loops; work from a master.
