Image Compressor

Shrink JPG, PNG, and WebP images to meet upload limits, speed up websites, or send lighter emails — with a quality slider so you stay in control.

Private by design: This tool runs entirely in your browser using its built-in image engine. Your files are not uploaded to a server, and nothing you convert is stored or logged.

How to use the image compressor

  1. Drop your images onto the upload area — JPG, PNG, and WebP all work, mixed batches included.

  2. Choose a quality level. 75% is a strong default: much smaller files, little visible change.

  3. Click Compress and compare the before/after sizes on each file.

  4. Download images individually, or everything as a ZIP.

Good to know

  • Each image keeps its own format — JPGs stay JPG, PNGs stay PNG, WebPs stay WebP.

  • JPG and WebP are compressed with the quality you choose. PNG is lossless, so its savings are smaller.

  • If compression can't make a file smaller, you get your original back unchanged — this tool never inflates a file.

Frequently asked questions

How much smaller will my images get?

Photos saved at high quality often shrink 50–80% at the 75% setting. Images that were already compressed shrink less — and if there's nothing to gain, we keep your original untouched.

Will compression make my images blurry?

At 70–85% quality, changes are hard to spot in normal photos. Heavy compression (below 60%) can soften fine detail and add artifacts — use the slider to find the balance you like, and convert again at a different setting any time.

Why did my PNG barely shrink?

PNG is a lossless format, so there's no quality slider to trade against size. If your PNG is a photo, converting it to JPG or WebP with our converters will save far more space.

Are my images uploaded anywhere?

No. Compression runs entirely in your browser — your images never leave your device.
