How this image compressor works

Drop in up to 20 images and choose one of two approaches. By quality re-encodes each photo at the level you set; most photos survive 70–80% with no visible change, because cameras save far more detail than screens can show. Exact size is for upload limits: enter a number in KB and the tool searches for the highest quality that fits under it, scaling dimensions down only as a last resort.

The compression itself happens in your browser. There is no upload step, which is why a 5 MB photo finishes in a second or two — the only thing that limits speed is your own device, not a server queue. It also means the tool works on sensitive material — ID scans, medical images, contract photos — without those files ever existing anywhere but your machine.

When to compress an image

  • An upload form rejects your photo for being too large.
  • Email attachments bounce or send slowly.
  • A website you run feels slow — image weight is the usual culprit.
  • Cloud storage or a phone backup is filling up with multi-MB photos.

Getting the best results

Start at 75% quality and look at the result before going lower — the preview numbers update on every run, so experimenting is free. Photographs tolerate compression well; sharp-edged graphics, text screenshots and logos show artifacts sooner, so keep those at 85% or above, or leave them as PNG. And compress from the original file when you can: re-compressing an already-compressed JPG stacks the losses from both passes.

If you have a hard ceiling to hit — 50 KB for a government form, 100 KB for a marketplace listing — the dedicated exact-size pages preset everything: just drop the file and download.

Frequently asked questions

What's the difference between the quality dial and exact size?
The quality dial re-encodes the image at the level you choose — 75% is a good default for photos. Exact size works backwards from a number: tell it 100 KB and it finds the highest quality that fits under that ceiling.
Can I compress several images at once?
Yes, up to 20 at a time. Each one is processed with the same settings, and you can download them individually or as a single ZIP.
Does compressing change the image dimensions?
Quality mode keeps the original width and height. Exact-size mode also keeps them when possible, and only scales the image down if the target can't be reached any other way.
Why did my PNG barely shrink?
PNG is lossless, so there's no quality dial to turn. For screenshots and photos saved as PNG, converting to JPG or WebP usually cuts the size by far more — try the PNG to JPG tool.
Is it safe for private photos and documents?
The image is processed by your own browser on your own device. It is never uploaded, so there is nothing on a server to leak, cache or delete.
