Image Compressor

Reduce JPG, PNG, or WebP images to under 50KB, 200KB, 1MB — or any size you need. Tell us the limit; we'll find the best quality that fits it, entirely on your device.

Free, with no signup and no watermark. Your images never leave your device.

JPG, PNG, WEBP
Your images stay on your device.
How small does it need to be?

We try WebP and JPG (or WebP/PNG if your image has transparency), search for the best quality that fits, and only shrink dimensions if quality alone can't get there.

Why target size beats a quality slider

Most compressors ask you to pick a quality percentage and guess. But the real question is almost never "what quality?" — it's "will this upload go through?" or "will this page load fast?" FitImage flips the problem around: tell us the limit, and we search for the highest quality that still fits under it.

What happens when a target isn't realistic

If 50KB genuinely can't be reached without ruining the image, we won't pretend otherwise. You'll see the best result we found, with the actual number, so you can decide whether to accept it or resize first.

Supported formats

  • JPG / JPEG — photos, no transparency
  • PNG — lossless, supports transparency
  • WebP — modern, strong compression, supports transparency

Common uses

  • Meeting a website's upload size limit
  • Speeding up a slow-loading page
  • Fitting under an email attachment limit
  • Preparing product photos for a marketplace

Frequently asked questions

Can I compress an image to an exact number of KB?
We target your limit as closely as possible and typically land just under it. Hitting an exact byte count isn't possible with lossy compression, but we always show you the real result.
Which format should I choose?
You don't have to — this tool automatically tries the best formats for your image (WebP first for photos, PNG or WebP if it has transparency) and picks the smallest one that meets your target.
Is this different from the JPG, PNG, or WebP compressor pages?
This page accepts all three formats and lets FitImage choose the best output automatically. The format-specific pages are for when you need to keep a specific output format, like JPG for compatibility.
Do you upload my images to a server?
No. Compression runs in your browser using the Canvas API. Your files never leave your device.
