About this tool
The Image Compressor reduces file sizes right in your browser with an adjustable quality slider and instant before/after comparison — no uploads, no file-count limits, no watermarks.
Oversized images are the number-one cause of slow pages, and page speed feeds directly into Core Web Vitals, search rankings, and bounce rate. Compressing a 4 MB photo to 300 KB is usually invisible to the eye and transformative for load time.
What people use it for
- Compress hero and product images before uploading to a website or store to protect page speed.
- Shrink photos to fit email attachment limits and form upload caps (many portals cap at 1–2 MB).
- Reduce screenshots for documentation, tickets, and READMEs where repositories penalize large binaries.
- Prepare batches of listing photos for marketplaces that recompress aggressively anyway — send them lean.
Tips for better results
- Quality 75–85% is the sweet spot for photos: substantial size reduction with differences the eye cannot resolve.
- Resize before you compress — a 4000px image displayed at 800px wastes bytes no quality setting can recover. The Image Resizer pairs well here.
- Keep original files for anything you may re-edit; recompressing an already-compressed JPG compounds artifacts.

- Download a test output and inspect it in the place where it will actually be used.
Quality and trust checks
- The interface keeps original and output states easy to compare.

FAQ
How much can I compress an image without visible quality loss?
For photographs, 60–80% file-size reduction is typically invisible at normal viewing sizes, especially with correct dimensions. Graphics with sharp edges and text show artifacts sooner — inspect the preview before downloading.
Are my images uploaded to a server for compression?
No — compression runs in your browser, so images never leave your device. That makes it safe for private photos, IDs, and unreleased product shots.
