Compresseur et redimensionneur d'images
Compressez et redimensionnez sans envoi.
Drag & drop an image here, or
JPG, PNG or WebP · nothing is uploaded — compression runs in your browser
Which format should I choose?
| Format | Best for | Transparency |
|---|---|---|
| WebP | Websites — usually 25–35% smaller than JPEG at similar quality | Yes |
| JPEG | Photos, email attachments, maximum compatibility | No |
| PNG | Screenshots, logos, text and sharp edges | Yes |
How to compress an image without uploading
- Drop a JPG, PNG or WebP image above — it stays on your device.
- Choose an output format. WebP gives the smallest files for websites.
- Lower the quality slider; 70–80% is usually visually identical to the original.
- Optionally resize with a preset or exact pixel size, then download the result.
Frequently asked questions
Is this image compressor private?
Yes. All compression uses your browser's built-in canvas. No file is sent to a server.
Why did my PNG get larger?
PNG is lossless, so re-saving can increase size. Switch to WebP or JPEG, or reduce the dimensions.
What quality should I use for the web?
Around 75% for JPEG or WebP keeps photos sharp while cutting file size by 60–80% in most cases.
Does resizing keep my metadata?
No. Canvas export removes EXIF data such as GPS location, which also improves privacy.
