How Image Compressor works

Cut image file size while the dimensions stay put. Choose a quality value, or give a target size in KB and let the tool pick the quality.

Image Compressor Details

Image Compressor reduces file size without touching the dimensions. Set a quality value, or name a target size in KB and let the tool work out the quality.

Whenever page speed, storage cost or upload time comes up, this is the first stop: the same image, noticeably lighter, with a loss most viewers never spot.

How to use it

The order follows the same logic as the converters:

  1. Add the images you want compressed to the upload area.
  2. Type a quality value between 20 and 95; the default of 82 is a sensible starting point.
  3. Aiming at a specific file size instead? Fill the target KB field rather than the quality field.
  4. Run the compression and compare the resulting size in the queue.
  5. Download it if you are happy, or change the quality and run the same file again.

Formats, limits and behaviour

The rules of the compression are straightforward:

  • Quality has to sit between 20 and 95; values outside that are rejected.
  • Target KB accepts 1 to 5120 and, when filled, decides the quality for you: the ratio against the source size is mapped into the 20 to 95 range.
  • For JPG, WebP and AVIF the quality value goes straight to the encoder.
  • PNG is lossless, so its savings come from reducing the colour palette rather than lowering quality.
  • Width and height stay exactly as they were; only the encoding changes.
  • Each file can reach 24 MB.

Picking the right tool

This is the right tool when the format should stay and the file should shrink. The target KB field earns its place against hard limits such as "this has to be under 200 KB".

If the dimensions are oversized too, resizing first saves more; if the format can change, a WebP or AVIF conversion delivers the same quality in a smaller file. Compressing an already compressed output stacks the loss, so start from the original each time.

Quick tips

  • For photographs, quality between 75 and 85 usually leaves a loss nobody notices.
  • Text, line art and screenshots break up at low quality, so stay above 82 for those.
  • Do not fill target KB and quality together; the target overrides the quality you typed.
  • Before publishing, zoom to 100% and check smooth gradients, where artefacts show first.

Data and privacy

Processing an image means uploading it, and that upload lives only as long as the request. Once the output exists, the file is not stored and never handed to a third party. Ads may appear on the page, but no ad network can reach your upload.

Frequently asked questions

For photographs, 75 to 85 usually looks identical to the original while cutting the file size noticeably. Choose a higher value for graphics with sharp edges; your original never leaves your machine, so a second attempt costs nothing.

Yes. Instead of picking a quality value, you can name a target size in KB and the tool finds the closest setting for you. That is handy for email attachments or upload forms with a size limit.
