How to compress an image to a target size

1Upload your imageDrop or select a JPG, PNG, or WebP file. The original size and dimensions are shown immediately, and a sensible target is pre-filled.

2Set the max sizeEnter the file-size ceiling in KB — for example 100 KB for a form upload or 68 KB for an email-friendly photo. You can optionally cap the dimensions too.

3Compress and downloadThe compressor first reduces quality at full resolution, and only scales the image down if quality alone can't reach the target — it tells you when that happens. Before/after size and dimensions are shown side by side.

FAQ

Will compressing reduce my image's resolution?

Usually not. The compressor is quality-first: it keeps your original pixel dimensions and lowers encoder quality to hit the target. Resolution is reduced only when the target is impossible at full size — and the result panel shows the dimensions so nothing changes silently.

What's the difference between compressing and resizing?

Compressing shrinks the file size (KB) while keeping the picture the same; resizing changes the pixel dimensions. If a portal asks for both an exact KB and exact pixels — like exam or passport uploads — use the Resize tool, which handles both together.

Is my image uploaded anywhere?

No. Compression runs in a Web Worker inside your browser — the file never leaves your device.

Is it free?

Yes — 30 edits per month free, no sign-up, no watermark, full resolution.
