Image Compressor
Shrink image file size without the fuss.
Drop an image to compress
PNG, JPG or WebP · drag & drop, paste, or click to browse
Runs entirely in your browser — nothing you enter is uploaded or sent to a server.
Compression is lossy — pushing the quality low enough will start to soften detail and colour, so glance at the result before you use it. Everything happens in your browser (nothing is uploaded), so very large images are limited by your device's memory, not by us. Read our full disclaimer.
About this tool
Image files are usually far bigger than they need to be — a photo straight off a phone can be several megabytes when a fraction of that looks identical on screen. This tool re-encodes your JPG, PNG, or WebP at a quality you choose, and can optionally cap the longest side, so pages load faster and uploads finish sooner. The work runs on your own device through the browser, so even a big photo never leaves your computer.
Roughly what to expect
A 4 MB phone photo at quality 75 with a 1920px cap usually lands around 300–600 KB — often 80% smaller — with no visible difference on screen.
How to use
- 1Drop in a JPG, PNG, or WebP — or click to browse.
- 2Pick a quality; 70 to 80 keeps photos looking clean while shedding most of the weight.
- 3Optionally cap the longest side, which is what really shrinks oversized camera photos.
- 4Compress, check the size saved, and download.
Features
- Quality dial from 10 to 100, with a live size read-out after compressing.
- Optional max-dimension cap (1920 / 1280 / 800px) for oversized photos.
- Tells you exactly how much smaller the result came out.
- Processed on your device — no upload, no queue, no watermark.
Frequently asked questions
Will compressing ruin the quality?
Not at sensible settings. JPG and WebP are lossy, so very low quality will soften detail — but 70 to 80 usually looks identical to the original at normal viewing size. Check the preview before downloading.
Is there a size or file-count limit?
There's no account and no per-file cap from us. The only real limit is your device's memory, because the whole job runs locally in your browser.
What's the difference between this and the resizer?
Compressing keeps the pixel dimensions but lowers the encoding quality to shrink the file; resizing changes the dimensions themselves. For the smallest possible file, resize first, then compress.
Do you keep a copy of my images?
No. They're never uploaded — compression happens in the browser and the result exists only on your device until you save it.
