Reduce the file size of your photos without losing noticeable quality — right in your browser. Whether you need to shrink an image for a website, email attachment, or online form with a size limit, this tool compresses JPG, PNG, and WebP files instantly, with no upload to any server and no sign-up required.

How to compress an image

  1. Select or drag and drop your image — JPG, PNG, or WebP files are supported.
  2. Adjust the quality slider to control how much the file size is reduced. Lower quality means a smaller file.
  3. Choose an output format. JPEG or WebP usually shrink file size the most; PNG stays lossless but won't shrink as much.
  4. Click "Compress Image" to see the before/after file size comparison, then download the result.

Frequently Asked Questions

Is this image compressor free to use?

Yes, it's completely free with no sign-up and no limit on how many images you can compress.

Are my images uploaded to a server?

No. All compression happens directly in your browser using your device's own processing power. Your images never leave your computer or phone.

Which format should I choose for the smallest file size?

JPEG or WebP will typically give you the smallest file size, since both use lossy compression. PNG is lossless, so it preserves more detail but won't compress as much — it's best for images with text, logos, or transparency.

Why didn't my PNG file get much smaller?

PNG is a lossless format by design, so the quality slider has limited effect on it. If you need a significantly smaller file, try switching the output format to JPEG or WebP instead.

Will compressing reduce the image quality?

Some quality loss is expected with JPEG and WebP compression, especially at lower quality settings. The before/after preview lets you compare visually and choose the best balance between file size and quality for your needs.

Can I compress multiple images at once?

Currently, this tool compresses one image at a time so you can review the before/after result for each one individually.

What's a good quality setting for web use?

Around 60-75% quality in JPEG or WebP usually gives a strong balance between visibly sharp images and a meaningfully smaller file size, which is ideal for websites and email attachments.
