How JPG compression works

JPG is where compression pays off most. Type a target size and Under1MB finds the highest quality that fits — often half the size or less with little or no visible change. Perfect for email, uploads, and anything with a limit.

Need to hit an exact number?

Target sizes live on their own pages, where the quality search runs against your limit.

Three things worth knowing about JPG

Quality is a dial

JPG lets you trade detail for size, which is where the big savings come from.

Compress from the original

Each lossy pass costs a little detail, so start from the master file rather than a file you already squeezed.

Nothing is uploaded

Your JPG is decoded and rewritten by the browser. Watch the network tab stay empty.

Questions

What quality should I use?+

Let Target size decide, or 60–80% by hand for most photos.

Can I go back to full quality later?+

No — compression is one-way, so keep your original.

Can it get my JPG under 1 MB?+

Almost always, without resizing.

Can I compress JPG files to an exact size?+

Yes — the size pages do that. Pick a limit like 500 KB and we search for the highest quality that fits underneath it.

Are my JPG files uploaded anywhere?+

No. Compression happens inside your browser, so the file never leaves your device and nothing is stored.

Is EXIF and GPS data removed?+

Yes. Re-encoding writes a clean file without camera, date or location metadata.
