When to use this tool

Compress images before uploading them to a website, attaching them to an email, or posting them on social media. Reducing file size helps pages load faster and keeps email attachments within size limits.

Quality tips

  • Product photos with smooth gradients tolerate lower quality (70–80 %) well. Screenshots with small text need higher quality (85 %+) to keep text readable.
  • Use the preview to compare before and after — a difference that looks obvious at 100 % zoom may be invisible at actual display size.
  • Different images respond differently to compression: a simple flat-color logo may compress far more than a busy landscape photo at the same quality setting.

Common mistakes

  • Over-compressing text-heavy images — thin letters become blurry or break apart, making the image hard to read.
  • Applying the same compression level to photographs, graphics, and screenshots without adjusting for content type.
  • Checking compression results only on a high-DPI screen — zoom to typical viewing size to see what visitors will actually experience.

FAQ

Image compression questions

Will compression upload images to the server?

No. This compressor uses browser Canvas APIs, so selected files stay on your device.

Which output format should I choose?

Choose WebP for most website delivery files. Choose JPG for systems that do not accept WebP or when you need a simple photo fallback.

Why can a compressed file become larger?

Small icons, already optimized files, or PNG graphics with flat colors may not shrink after canvas export. Compare the result before replacing originals.

Is Image Compressor free to use?

Yes. Image Compressor is completely free. There is no sign-up, no watermark on the output, and no usage limit for standard conversion.

Can I use Image Compressor on a phone or tablet?

Yes. Image Compressor runs in any modern mobile browser including Safari on iPhone and Chrome on Android. No app installation is required.

Do you keep a copy of my files when I use Image Compressor?

No. Image Compressor processes images entirely in your browser. Your files are never sent to a server, stored, or logged anywhere.

What input formats does Image Compressor accept?

What output formats can Image Compressor produce?

How many images can I process at once with Image Compressor?

Does Image Compressor reduce image quality?

It depends on the output settings. You can adjust the quality slider before downloading to find the right balance between file size and visual detail.

Does Image Compressor work without an internet connection?

Once the page has fully loaded, Image Compressor can process images offline because all conversion happens inside your browser rather than on a remote server.

What is the maximum file size Image Compressor supports?

File size limits depend on your device's available memory. Very large images may take longer to process or require a device with more RAM to complete reliably.

Do I need to create an account to use Image Compressor?

No account or sign-up is required. Open the tool, choose a file, and download the result immediately.

Will Image Compressor work on my desktop computer?

Yes. Image Compressor works in all major desktop browsers including Chrome, Firefox, Safari, and Edge on both Windows and macOS.
