Compress images free — in your browser, with nothing uploaded

Most compressors make you upload your photos, then hand back a file and hope you like it. This one runs in your own browser and shows you the result next to the original, with a divider you can drag, so you can push the quality down exactly as far as the picture will take and no further.

Your pictures never leave your browser

Other image sites upload your photo to a server, then watermark it, cap how many you can do, or ask you to pay. This one uses your browser’s own image engine, so nothing is transmitted — and because there is no library to download, these pages work with no connection at all, from the very first visit.

What you can do

See what you are losing — original and compressed in the same frame, with a divider you drag.

Three formats — JPG, WebP or PNG, or keep whatever you started with.

Many at once — drop a folder full, download them individually or as one ZIP.

Resize while you are at it — shrinking a 4000px photo to 1920px usually saves more than any quality setting.

No watermark, no account, no cap — unlike most free compressors.

Nothing uploaded — your photos stay on your device.

Frequently asked questions

Are my photos uploaded anywhere?

No. The compression is done by your browser’s own image engine and the result is saved straight to your downloads. Nothing is transmitted — which also means there is no queue, no size cap and no daily limit.

Which format should I choose?

For photographs, WebP is smallest, typically 25–35% below JPG at the same visible quality, and every current browser reads it. Choose JPG if something old has to open the file. Choose PNG only for graphics with sharp edges or transparency — for a photograph it will be several times larger.

Why did my PNG barely get smaller?

Because PNG is lossless: it stores every pixel exactly, so the quality slider has nothing to trade away. A screenshot or logo will shrink a little. A photograph will not — convert it to JPG or WebP instead, which is what the format menu is for.

Why did my file come out bigger?

It was already better compressed than this setting produces — that happens with pictures that have been through a compressor before, and with PNG output. The tool tells you when that occurs rather than quietly handing back a worse file; lower the quality, or change format.

Does it strip the EXIF data?

Yes. Re-encoding through the browser drops the metadata, so the camera model, the timestamp and any GPS position in the original are not carried into the new file. That is usually what you want before putting a photo online. Keep your original if you need the data.

Can it open my iPhone photos?

Only in Safari. HEIC is Apple’s format and no other browser can decode it. On your iPhone, Settings → Camera → Formats → “Most Compatible” makes the camera save JPEGs, which work everywhere.

Is it free?

Yes, completely — no account, no limits, and nothing added to your pictures.
