Compress Images Online — Free, No Upload Required
Compress targets file size specifically — same dimensions, smaller footprint — by tuning the encoding rather than changing what’s in the image. Useful when a form, email, or upload limit rejects a file for being too heavy, not for being too big in pixels.
How to use it
Upload the image, drag the quality slider (or set a target file size directly), and watch the live before/after size comparison update. For PNGs, the tool applies lossless optimization; for JPEG/WebP, it adjusts the compression level. Export once you’ve found a size/quality balance you’re happy with.
Common situations this solves
- Getting a photo under an email attachment limit
- Meeting a website’s max-upload-size rule for a profile picture
- Reducing page-load weight for images you’re embedding somewhere
- Shrinking a large scan or screenshot before messaging it
- Preparing multiple product photos to a consistent, lighter size
FAQ
Will compression make my image blurry? At moderate settings, no — you’re removing redundant data most eyes won’t notice; pushed too far, yes, you’ll start to see blocky artifacts, which is why the live preview is there to catch that point before you export.
What’s the difference between this and Resize? Compress keeps the same pixel dimensions and reduces file size through encoding; Resize changes the dimensions themselves. Combining both gets you the smallest possible file when a target is tight.
Is PNG compression here lossless? Yes — PNG compression re-encodes the file more efficiently without discarding any pixel data, unlike JPEG/WebP compression which does trade quality for size.
Can I hit an exact target file size, like “under 200KB”? Yes, enter the target and the tool will estimate the closest quality setting to get there.
Does compressing strip metadata? Not by default — if you also want camera/location metadata removed, run the file through Bare — metadata stripper.
