Compress Image
Make photos and graphics smaller without making them look worse. Compress many JPG, PNG and WebP files at once, see how many kilobytes you saved and download them in one ZIP.
- Batch compress
- JPG, PNG, WebP
- Never bigger than the original
Loading the Compress Image tool...
Your images are processed by your own browser. Nothing is uploaded to a server, so your photos stay private and the tool keeps working even on a slow connection.
How to use the Compress Image tool
- Select your images, drop them on the box or paste a screenshot with Ctrl+V.
- Set the quality. 70 to 85 keeps photos looking the same at a fraction of the size.
- Keep the same format or switch to WebP for the smallest files on websites.
- Optionally set a maximum width: a 4000 px phone photo rarely needs to be wider than 2000 px.
- Click Compress images and download each image, or all of them as a ZIP.
Why use this compress image tool
- Faster websites. Smaller images load faster, which helps visitors and search rankings.
- Email and forms. Fit photos under upload limits for email, job portals and government forms.
- PNG too. PNG graphics are reduced with smart colour reduction, transparency is kept.
- Honest results. If a file can't get smaller, you get your original back instead of a bigger copy.
Frequently asked questions
How much can I compress a JPG?
Most phone photos shrink by 60 to 80 percent at quality 80 with no visible difference. Lower the quality or the maximum width for even smaller files.
Will compressing reduce the quality?
JPG and WebP compression removes detail the eye barely sees. Compare the before and after sizes and pick a higher quality if you need the image for print.
Can I compress a PNG and keep transparency?
Yes. PNG files are compressed by reducing the number of colours, and transparent areas stay transparent.
Is there a file size or number limit?
There is no fixed limit because the work happens on your device. Very large batches simply take a bit longer.
Are my images uploaded?
No. The compression runs in your browser, so your files never leave your computer or phone.
