Image Compressor FAQ

How do I compress an image without losing visible quality?

Start at 80% quality. Most photos shrink substantially with no visible change; lower the slider further only if you need a smaller file.

Which formats are supported?

JPG, PNG, and WebP.

Is my image uploaded?

No. The file is processed by JavaScript inside your browser tab and never sent to our servers. Closing the tab clears it from memory.

Why is my PNG still large?

PNG is lossless, so it compresses less. Converting to JPG or WebP with the Image Converter usually gives a much smaller file.

Is it free?

Yes — no sign-up and no watermark.

Quick answers

How can I compress images for the web without losing visible quality?

Start with the right format: photographs usually compress best as JPG or WebP; graphics with flat colour suit PNG. Upload the image, set quality around 75–85%, and compare before/after at 100% zoom. A good compressor removes invisible metadata and applies smart chroma subsampling so file size drops 50–70% while looking identical on a phone screen. For hero images, also resize to the display width you actually need — shrinking dimensions saves more bytes than aggressive quality cuts. Browser-based compression keeps photos on-device, which helps GDPR-sensitive sites and client galleries. After export, run Lighthouse or PageSpeed Insights on the page to confirm LCP improvements. EasyPDFHub’s image compressor is free and runs locally in your browser.
