Questions

Frequently asked questions

How much smaller will my images get?

Phone photos are saved at 95–100% quality. Re-encoding at 80% often cuts 60–85% of the file size with no visible change. PNG screenshots shrink more when converted to JPG or WebP. Already compressed images shrink less.

Does compressing reduce quality?

JPG and WebP compression discards fine detail. Between 75% and 90% quality, the result is visually identical to the original. Below 60%, you may see softness and blocking in areas like sky or skin.

Should I choose JPG or WebP?

WebP files are 25–35% smaller than JPG at the same quality and supported by all modern browsers. Choose JPG for compatibility with older software. Choose PNG only when you need a lossless copy without any compression.

Is there a file size or daily limit?

No. Add files of any size, as many as you like, as often as you like. Everything is processed on your device, so the only limit is your device’s memory.

Are my images sent anywhere?

No. Your files are processed in your browser and are never sent to a server. All work happens on your device, so nothing is stored. The tool even works if you go offline after the page loads.

Background

What actually makes an image file big

Choose a quality, optionally cap the longest side, and watch the before-and-after size for every file. Camera photos typically lose 60–85% of their bytes with no visible change.

  • A photo’s size depends on its dimensions, quality, and format. A 12-megapixel photo has 4x more pixels than a 1920px screen can show.
  • Cameras save at high quality for editing. WebP is smaller than JPG, which is smaller than PNG for photos. This tool lets you adjust all three.
