How to use the Free Image Compressor
- Drop your images into the box, click choose files, or paste with Ctrl+V.
- Choose Quality (75 is a good start) or Target file size if a form or website has a size limit.
- Optionally set a Max width and convert to WebP or JPG. These usually save the most.
- Drag the slider on the preview to compare the original and compressed image. Click any thumbnail to compare it.
- Click Download, or Download all (.zip) for several images.
How much smaller will my images get?
Phone photos usually shrink by 60–90% at quality 75–85 with no difference you can see on screen. Images that were already compressed, such as pictures saved from social media, shrink less. If the result would be larger than your original, the compressor keeps the original file instead, so you never end up with a bigger image.
Compress to an exact size (like 100 KB or 1 MB)
Job portals, visa forms and email often have a size limit. Choose Target file size, enter the limit, and the compressor finds the highest quality that fits. If even low quality is too big, it gently reduces the pixel size until the image fits. Each result shows its final size, so you can check it before uploading.
Which format gives the smallest file?
- WebP: typically 25–35% smaller than JPG at the same quality, and it keeps transparency. Best for websites.
- JPG: works everywhere, including old software and printers. Best for photos you'll share or upload to forms.
- PNG: lossless and sharp for screenshots, logos and text, but large for photos. Converting a photo from PNG to JPG or WebP often cuts the size by 90%.
Faster websites and emails
Large images are the most common reason web pages load slowly. For a website, a width of 1600–1920 px at quality 75–80 in WebP is plenty for full-screen images. Smaller files also mean faster email attachments and less mobile data for the people you send them to.
Private by design
Most online compressors upload your photos to their servers. This one doesn't: compression runs inside your browser. As a bonus, compressing removes hidden photo metadata such as camera details and GPS location.
Frequently asked questions
Is this image compressor free?
Yes. It's free with no sign-up, no watermark and no limit on the number of images or their size.
Will compressing reduce the quality?
JPG and WebP compression removes detail your eyes don't easily notice. At quality 75–85 most photos look identical to the original. Use the before/after slider to check, and raise the quality if you see any difference.
How do I compress an image to 100 KB?
Choose Target file size, enter 100 and select KB. The compressor picks the best quality that fits under 100 KB, and shrinks the image slightly only if necessary.
Are my images uploaded?
No. Everything runs in your browser on your own device, so your photos stay private and it works even with a slow connection.
Why didn't my PNG get much smaller?
PNG is a lossless format, so there's little to remove. Switch the format to WebP (keeps transparency) or JPG (for photos) for a much smaller file.
Does it remove location data from photos?
Yes. Compressed images are saved without the original metadata, including GPS location and camera details. Only files kept as the original are unchanged.
Can I compress many images at once?
Yes. Add as many as you like, and they're all compressed with the same settings. Download them one by one or as a single zip file.
