Compress an image without resizing it
Shrink a photo's file size for faster page loads or smaller email attachments, while keeping its original width and height untouched.
What is Image Compressor?
This image compressor re-encodes your photo at a lower internal quality setting to reduce its byte size, without changing how big it looks on screen. Use it to compress an image for email attachment limits, shrink a photo for faster website loading, or reduce a picture's file size before uploading it somewhere with a size cap — all without touching its pixel dimensions.

Common questions
Does compressing reduce image quality?
Some, depending on the strength you choose — higher quality keeps more visual detail at a larger file size, lower quality shrinks the file further with a more visible trade-off.
Can I also resize while compressing?
Yes — turn on "Resize before compressing" under Advanced settings if you also want smaller pixel dimensions, not just a smaller file size.
How much can I compress an image without visible quality loss?
The Recommended setting is tuned to stay visually close to the original for most photos — try that first, then move toward Smaller file only if you specifically need a lower file size, e.g. for an email or form attachment limit.
What is the best free way to compress an image online?
A tool that shows you the exact before/after file size and lets you pick the quality level yourself — like this one — gives more control than a fixed-preset compressor and never requires an account or software install.
