Image Compressor & Converter
Free with accountUp to 20 files · 10MB each · metadata strippedShrink JPG, PNG and WebP images and convert between formats — in batches, entirely in your browser. No daily limits, no uploads: your files never leave your device.
80% is visually lossless for most photos. PNG ignores quality (lossless format) — convert to WebP or JPG for the biggest savings.
Files are processed on your device and never uploaded. Re-encoding strips EXIF metadata (location, camera info) — a privacy bonus. "To Hub" is the one exception: that click uploads that result to your own Media Hub.
Which format should you use?
The honest answer, in one card each
Smallest files at the same visual quality — typically 25–35% smaller than JPG. Supported by every modern browser.
The universal photo format. Great compression for photographic content; no transparency.
Lossless, pixel-perfect, supports transparency. Larger files — use it for logos and UI, not photos.
How it works
Three steps from heavy to light
Add your images
Drag and drop up to 20 images at once, paste from the clipboard, or browse. JPG, PNG and WebP up to 10MB each.
Pick format & quality
Keep the original format or convert everything to JPG, PNG or WebP. Set the quality and optionally downsize to a maximum dimension.
Compress & download
See the before and after size of every file, download them one by one or grab everything as a ZIP.
Everything you need
Built for batches, built for privacy
No daily limits
Popular compressors cap you at 20 files or a handful of tasks per day. Here there are no caps — compress as much as you need.
100% private
Everything runs in your browser. Your images are never uploaded to a server — safe for client work and unreleased material.
Batch + ZIP
Process up to 20 images in one go with live before/after sizes per file, and download the lot as a single ZIP.
Metadata stripped
Re-encoding removes EXIF data — location, camera and device info — from every output file. A privacy bonus by design.
Frequently asked questions
Is this really free?
Yes — completely free with any Fast Media account, including the free tier. No daily task limits, no file-count caps, no watermarks.
How much smaller will my images get?
Photos typically shrink 60–80% at 80% quality with no visible difference. PNG is a lossless format, so its savings come from downsizing — converting PNGs to WebP usually gives the biggest reduction.
Which format should I choose?
WebP gives the smallest files and is supported by every modern browser — best for the web. JPG is the safe universal choice for photos. PNG is for graphics that need transparency or pixel-perfect edges.
Are my images uploaded anywhere?
No. Compression happens entirely in your browser using the canvas API — your files never leave your device.
What happens to transparency?
PNG and WebP keep transparency. JPG doesn't support it, so transparent areas are filled white when converting to JPG.
Does it remove EXIF data?
Yes — re-encoding strips all metadata, including GPS location and camera details. If you need to keep EXIF, keep your originals.
