Image Compressor
Shrink JPG, PNG and WEBP file sizes without visible quality loss.
Quick answer: The fastest way to shrink a JPG or PNG is re-encoding at quality 75-85, which typically cuts file size 60-90% with no visible difference at normal viewing sizes. The compressor below does it in your browser with a live preview - no upload, no size caps, no daily limits.
This compressor re-encodes your image at a quality level you control, with a live before/after preview so you can see exactly what you're trading. It runs entirely in your browser — no upload, no queue, no daily limit.
Typical results: photos shrink 60–90% at quality 75–85 with no visible difference at normal viewing sizes.
How it works
- Drop an image (JPG, PNG or WEBP).
- Pick an output format and move the quality slider — the compressed size updates live.
- Compare before/after, then download. Nothing is uploaded anywhere.
Good to know
- PNG output is lossless, so the size reduction for PNG-to-PNG comes only from re-encoding and resizing — converting graphics to WEBP usually saves far more.
- Compressing an already-compressed JPG repeatedly degrades it; always keep your original.
Frequently asked questions
How is this different from TinyPNG?
Two ways: there is no 5 MB file cap and no 20-image batch limit, and your image is never uploaded — compression happens on your own machine, so it's private and fast.
What quality setting should I use?
For photos on the web, 75–85 is the sweet spot. For images people will zoom into, use 85–92. Below 60 you will start to see compression artifacts around edges.
Does compressing an image reduce its print quality?
Lossy compression discards fine detail, so for print or embroidery digitizing always send the original, uncompressed file. Compress copies for email and web use.
