How our free tool compares
- What you get for free. Convert between JPG, PNG and WebP, turn iPhone HEIC photos into JPG, set the quality and scale images down to a maximum width or height, with no watermark and no account.
- Limits. Up to 30 images per batch. Avalon Pro takes up to 500 at once and adds ZIP downloads, saved presets, custom file names and a panel to see each photo's info and choose what to keep. The conversion itself is the same on every plan.
- Same engine, other pages. The same free tool also has pages set up for HEIC to JPG, PNG to JPG and general image conversion.
- Privacy. Everything runs in your browser, so your photos are not uploaded to us.
- What TinyPNG does that we do not. TinyPNG can output AVIF, which our converter does not, and it offers a developer API and a WordPress plugin. We have not run a side-by-side test of its compression against ours, so we make no claim about which gives smaller files at the same quality. Try your own images and compare the sizes shown.
