Is this tool really free?

Yes. No sign-up, no watermark, no hidden limits for files under 25 MB.

Do you keep my images?

No. Uploads are deleted the moment the response is sent back to you. We never log, cache, or train on them.

Why does the target size mode look slightly off?

JPEG compression is non-linear, so we binary-search for the closest quality that lands within 5% of your target. Expect ±2KB on small images.

Does compressing hurt image quality?

A tiny bit. At quality 80, most people can't tell the difference. Below 50, you'll start to see artifacts — stick to 60+ for photos.

Which format should I pick?

Keep original unless you have a reason. WebP is ~25% smaller than JPEG at the same quality but isn't supported by every email client yet.

Can I compress PNGs losslessly?

Pick PNG as the output format and set quality to 100. We'll strip metadata and re-encode without touching pixels.

Compress image to a target size

Shrink JPEG, PNG, and WebP images down to an exact KB size — without losing visible quality.

Drop a file

.jpg, .jpeg, .png, .webp · up to 25 MB

How should we compress?

Quality keeps the image sharp. Target size forces a specific KB.

Quality

Higher = better quality, larger file. 80 is a good default.

Output format

Compressing images is the single fastest way to speed up any website, cut email attachment sizes, and save storage. This tool uses perceptual quality scoring combined with a binary search over encoder settings to hit an exact target size — something most compressors can't do. Your image never touches a third party: it's processed on our server, returned to you, and deleted immediately.

How to use compress image to a target size

1
Drop your image
Click the drop zone or drag any JPEG, PNG, or WebP file into it. Files up to 25 MB are supported.
2
Pick quality or target size
Choose quality (80 is a good default) or switch to target size and type a number in KB — like 50 for a 50KB thumbnail.
3
Press Compress
We process the image on our server. Large images take a second or two; most finish instantly.
4
Download the result
Your compressed image is ready to download. Source file is deleted from our servers immediately.
