About the Image Compressor
Big photos slow down websites, bounce off email size limits and fill up phone storage. This free image compressor shrinks JPG, PNG, WebP and AVIF files online: pick a quality level, upload your picture and download a much lighter copy in the same format.

Frequently Asked Questions
How do I reduce the file size of an image?
Upload the image above, leave the quality slider at 75 (or lower it for a smaller file) and click Compress. The tool re-encodes the picture with an efficient encoder and gives you a smaller copy in the same format to download.
Does compressing an image reduce its quality?
Compression removes detail your eye rarely notices, so at quality 70–80 most photos look identical to the original. Very low settings (below 40) can show blockiness, so raise the slider if you spot artifacts.
What is the best quality setting for compressing photos?
For the web, 70–80 is the sweet spot between size and sharpness. Use 85–90 for prints or portfolio images, and 50–60 when you need the smallest possible file for email or upload forms.
Which image formats can I compress?
JPG/JPEG, PNG, WebP and AVIF. The compressed file keeps the original format, so a PNG stays a PNG and a JPG stays a JPG.
How much can an image be compressed?
Typical camera and phone photos shrink by 50–80%. Images that were already heavily compressed, or small graphics, shrink less because there is little redundant data left to remove.
How do I compress an image to under 100 KB or 200 KB?
Use our Compress to Specific KB/MB tool, enter the target (for example 100 or 200 KB) and it automatically finds the highest quality that fits under that size.
Why is my PNG still large after compressing?
PNG is a lossless format, so quality settings matter less. Try Compress PNG, which reduces the number of colours, or convert the image to JPG or WebP if it has no transparency.
Can I compress several images at once?
Yes. Use the Bulk Image Compressor to upload many images in one go and download them all compressed in a single ZIP file.
Is it safe to compress images online here?
Yes. Your image is processed in memory for this one request and discarded immediately. Nothing is saved, logged or shared, and there is no account to create.
Can I compress images on my iPhone or Android phone?
Yes. The compressor works in any mobile browser — tap the upload box, choose a photo from your gallery and download the smaller copy straight to your phone.
