How it works

JPG Compressor in 4 steps

  1. Drop a JPG onto the tool or click Choose File.

  2. It compresses instantly at 75% quality - a strong default for photos.

  3. Drag the slider and watch the size readout; compare the previews for blockiness around edges.

  4. Download when the balance is right.

When to use it

JPEG is already a compressed format, so shrinking it further is a balancing act: every quality point you give up buys file size. This compressor re-encodes your JPG on your device with a live before/after readout, so you can stop exactly where artifacts would start to show.

  • Get photo email attachments under a 10MB or 25MB cap.
  • Compress product photos so listings load fast without visible loss.
  • Shrink a whole shoot before uploading to a gallery with Pro batch.

Format & quality notes

  • JPGs that were already heavily compressed won't shrink much more without visible artifacts - the readout will tell you honestly.
  • Blockiness shows first in smooth gradients (skies, skin) and around sharp edges; check those areas in the preview.
  • Compression re-encodes the file, which also strips EXIF metadata from the output.
FAQ

Questions about the JPG Compressor.

What quality level should I use for JPG?

70-80% is the sweet spot for photos - big savings with changes most eyes can't see. Below 60%, gradients start banding and edges get blocky.

Why won't my JPG get any smaller?

It was probably compressed aggressively already - re-compressing an already-small JPG mostly re-encodes the existing artifacts. Try resizing its dimensions instead; that's where the remaining savings live.

Does compressing a JPG again ruin it?

Each re-encode loses a little detail (generation loss). One pass at a sensible quality is fine; avoid compressing the same file over and over.

Is my photo uploaded?

No. Compression runs in your browser - the photo never leaves your device.
