How to compress an image
Add your images
Drag up to 20 images onto the drop zone, or click to pick them. JPG, PNG, WebP and any other format your browser can display are accepted.
Set format, dimensions and quality
JPEG for a photo, WebP for an even lighter file, PNG when the image must stay lossless. Cap the longest side at 2,048, 1,600 or 1,200 px when the image is meant for a screen. The quality slider starts at 70.
Download
Each result shows its size before and after, with the percentage saved. Grab files one by one, or all together as a ZIP.
When to use it
A rejected attachment
A form caps uploads at 2 MB, a mail service limits the whole message: a 4 to 6 MB phone photo drops below 600 KB as JPEG 70 at 1,600 px.
Faster web pages
Images are often the heaviest thing on a page. Export as WebP at the width actually displayed rather than at sensor size.
A listing or a product page
Platforms recompress whatever you upload. Starting from a clean 1,600 px file avoids a double quality loss and shortens the upload.
A batch of photos to archive or share
Process 20 images in one go with the same settings and download a single ZIP.
What we measured
- On three phone photos of 3.7 to 6.4 MB, lowering quality to 70 without touching dimensions saves 55 to 57%. Adding a 1,600 px cap raises the saving to 91–93%. Dimensions matter far more than the slider.
- At the same slider value, WebP is only 5 to 11% lighter than JPEG. At comparable fidelity (WebP 50 against JPEG 70) the gap grows to 24–31%, for an encode 6 to 7 times slower.
- For a screenshot, JPEG is a poor choice: −36% at quality 70 with degraded text, against −73% as WebP.
- PNG output does not suit photos: 37 seconds of work for −7% in our test, and the image may be scaled down to stay under 10 MB. Keep it for logos and screenshots.
- An image is never enlarged: if it is smaller than the chosen cap, its dimensions stay unchanged.
- In both modes the output file holds no metadata (EXIF, GPS position). "Browser" mode: the image is re-encoded on your device. "Server" mode: metadata of JPEG, PNG and WebP files is removed on your device before upload, then the image is processed in memory without being stored, up to 10 MB.
Frequently asked questions
Which quality should I pick for a photo?
Between 70 and 80 as JPEG, the difference from the original is not visible at normal display size. Below 50, blocks appear in flat areas and around text. Start by reducing dimensions: that is where most of the saving is.
Are my images uploaded to a server?
Not in the default "In your browser" mode: all the work happens on your device, which you can check in your browser's Network tab. The "On our server" mode uploads the image, which is processed in memory and sent back without being kept.
Does compression remove the GPS position from my photos?
Yes, in both modes: the output file holds neither EXIF nor position. In server mode that data is removed on your device before upload, so it never leaves your phone or computer. To check a file before publishing it, run it through the metadata viewer.
Is there a size limit or a watermark?
No watermark, no sign-up. In browser mode the limit is your device's memory; in server mode, 10 MB per image. A batch holds at most 20 images.
Should I compress or resize?
Both, in that order: first bring the image down to the size you need, then pick the quality. The "Max dimensions" setting does both in one pass; for exact dimensions or a crop, use the resize tool.
