About the Image Compressor tool
Compress JPG, PNG, and WebP images by up to 90% without visible quality loss. Drag the quality slider for instant results, or type a target size and Pixveil's smart search finds the best quality that fits under it.
Compression happens in your browser, so there is no upload wait and no cap imposed by a server. The only limit is your device's memory.
How the compression works
Photos are large because they store far more detail than a screen actually shows. The Image Compressor re-encodes your JPG, PNG, or WebP at a smarter quality level, discarding data your eye can't see while keeping the picture sharp. Drag the quality slider for instant control, or type a target size in KB and Pixveil runs a quick search to find the highest quality that still fits under your limit — handy when a form says "max 2 MB" or "under 500 KB".
What people use it for
- Email & uploads — get a photo under an attachment or form size limit without resizing three times.
- Faster websites — lighter images load quicker and help your Core Web Vitals and SEO.
- WordPress & blogs — shrink featured images so pages stay fast on mobile.
- Storage & sharing — fit more photos in the same space, or send them faster on a slow connection.
Tips for the best quality-to-size ratio
- Use JPG for photographs and PNG only when you need transparency or crisp text and lines.
- If a file is still large, reduce its pixel dimensions first with the Image Resizer — a 6000px photo rarely needs to stay that big.
- Compress once from the original; repeatedly re-compressing the same JPG slowly degrades it.
Frequently asked questions
Will compressing lower the quality? A little data is removed, but at sensible settings the difference is invisible — you typically save 50–90% of the file size with no noticeable change.
Is there a file-size or daily limit? No limits and no sign-up. Compress as many images as you like, free forever.
Are my images private? Completely. Compression happens in your browser, so files are never uploaded to a server.
Which formats are supported? JPG, PNG, and WebP, both in and out.
