Frequently Asked Questions

Photographs usually shrink by 50 to 80 percent with no visible change, while PNG screenshots can drop by 70 to 90 percent. Images that have already been compressed heavily will save less because there is little redundant data left to remove.
Not in a way you will notice at normal viewing sizes, because the algorithm discards detail the eye cannot resolve. If you zoom to 100 percent on a large print you may find very fine detail has softened, so keep your untouched master.
Yes, entirely. There is no sign-up step, no watermark and no daily conversion allowance to run out of.
No. Files are processed in temporary storage and deleted once the download is complete, so your originals are not retained or shared with anyone.

About Image Compressor

Images are usually the heaviest thing on a web page. A handful of unoptimised product photos can add several megabytes before a visitor sees a single line of text, and on a phone that is the difference between a page that loads and a page that gets abandoned. Compressing images is the single highest-return optimisation most sites never do.

This compressor handles jpg, jpeg, png and webp uploads of up to 20 MB. It re-encodes the image with the same format and the same extension you uploaded, applying a well-tested compression algorithm that strips out data the eye cannot see. The result is a file that looks the same at normal viewing size but weighs a fraction as much. The tool shows the before and after size and the percentage saved so you can judge for yourself.

Because it runs server-side, you get the same result whether you are on a desktop, a tablet or a phone, and there is no need to install anything or upload your files to a third-party image host first.

When to Use This Tool

  • Before uploading photos to WordPress, Shopify, Squarespace or any CMS that stores the original file untouched
  • Getting a page under a weight budget so it passes PageSpeed Insights and Core Web Vitals
  • Squeezing images into a form with a 1 MB or 2 MB upload ceiling for a client, marketplace or government portal
  • Cleaning up an email newsletter or chat message where several large attachments get rejected or truncated
