Image Compressor

Compress JPG, PNG, and WebP images online for free. No upload required, fast, secure, and easy to use in your browser.

Checks that make image editing safer

Before editing

  • Keep the original image and edit a copy when possible.
  • Check the final size requirements for social posts, blogs, forms, or documents.
  • For images with text or logos, make sure cropping and resizing will keep them readable.

After editing

  • Preview the result on both mobile and desktop if it will be published online.
  • If the file is still large, use image compression before publishing or sharing.
  • Compare visual edits such as watermarking or grayscale with the original to confirm the result fits the goal.

Common next steps

What is Image Compressor?

This free image compressor helps you reduce the file size of JPG, PNG, and WebP images directly in your browser. It is useful for blog images, ecommerce product images, social media assets, portfolio screenshots, and other web graphics. Smaller files can improve page speed, reduce upload time, and save storage space. Since processing happens locally in your browser, your files are not uploaded to an external server.

When image compression helps most

Compression is especially helpful for blog images, ecommerce product photos, portfolio screenshots, slide decks, social media assets, and any upload where speed or file limits matter.

Smaller files can improve page speed, shorten upload time, reduce storage usage, and make image-heavy pages feel much faster.

How to choose the right approach

For photos, lowering quality a little often saves a lot of space with only a small visual tradeoff. For PNG graphics, size savings can be more limited depending on the image structure.

A practical starting point is quality 80, then move downward only if the result still looks good at the size people will actually view.

Tips for better results

  • Do not over-compress text-heavy images, because small text and sharp edges can degrade quickly.
  • Product shots and portraits often work well in the 70 to 85 quality range.
  • If PNG files barely shrink, try converting to JPG or WebP instead.
  • Combining resize and compression often gives a much better result than compression alone.

Output format tradeoffs

Keep original format
Best when you want a safer first pass without changing the overall workflow or file type.
Convert to JPG
Usually a strong choice for photos and general lightweight sharing. Transparency is lost.
Convert to WebP
Often the most efficient choice for web delivery when compatibility requirements allow it.
Export as PNG
Useful for graphics or transparency, but often less effective for aggressive file-size reduction.

How to Use

  1. Upload an image file
  2. Adjust the compression quality with the slider
  3. Choose an output format if needed
  4. Click the Compress Image button
  5. Preview and download the compressed image

FAQ

Are my images uploaded to a server?

No. Everything is processed locally in your browser, so your files are not uploaded to an external server.

Can I compress PNG images too?

Yes. PNG images can also be compressed, although the size reduction may be smaller compared to JPG or WebP.

What quality setting should I use?

A range of 70 to 85 is a good starting point for most images. Around 80 often gives a good balance between quality and size.

Does it work on mobile devices?

Yes. You can use it on phones, tablets, and desktop browsers that support modern web features.
