Compress Images for Email and Web — Without Losing Visible Quality
Big photos stall email and slow down websites. Here's how to compress images in your browser, keep them looking sharp, and never upload the originals to a server.
A single photo from a modern phone can be 3–8 MB. Attach a few to an email and it bounces. Drop them on a webpage and it takes forever to load. You need smaller files — but you don't need to hand your photos to a cloud service to get them.
Why compress images at all
- Email limits. Most providers cap attachments around 20–25 MB total.
- Page speed. Google ranks faster sites higher, and images are usually the heaviest thing on a page.
- Storage. Compressed photos free up space without deleting memories.
Compress locally, keep the quality
Our image compressor runs entirely in your browser:
- Drop in your JPG or PNG (it also handles WebP and AVIF).
- Pick a target size or quality level.
- Preview the result and download.
Because it runs on your device, the original photo is never uploaded. You see a side-by-side preview so you can stop before quality drops.
Tips for the best results
- Start with JPG for photos. PNG is lossless, so it compresses less — use JPG unless you need transparency.
- Don't over-shrink. 70–85% quality is usually invisible to the eye but cuts file size dramatically.
- Resize first if needed. A 4000×3000 photo destined for a 800px-wide blog column should be resized, not just compressed.
If your source is an iPhone HEIC, convert it to JPG first, then compress. And if you're preparing product shots, our background remover pairs well before export.
The private alternative to "cloud compressors"
Cloud tools often keep copies of what you upload "for a while." For innocuous screenshots that may be fine — for personal or work photos, doing it on your device removes the risk entirely.
