How to compress a JPG in 3 steps
Drop your JPG or JPEG files into the box above, or click to browse. Riducly compresses each one instantly in your browser. Then download the optimized photos one by one, or all at once as a ZIP.
How JPG compression works
JPG is a lossy format: it saves space by discarding detail the eye barely notices, mostly in smooth gradients and fine texture. Lowering the quality setting removes more data and shrinks the file further. Riducly re-encodes your photos at an efficient quality so they stay sharp while weighing far less.
Choosing the right JPG quality
A quality around 75–85% is the sweet spot for most photos: large savings with no visible loss. Push lower for thumbnails or previews where size matters most, and keep it higher for images with text or hard edges, where JPG artefacts show up first.
JPG, PNG or WebP? When to convert
Keep JPG for photographs that need universal compatibility across browsers, email and devices. Convert to WebP when you want even smaller files for the web. Choose PNG only when you need transparency or pixel-perfect graphics. Riducly handles all three from the same tool.
Frequently asked questions
Does compressing a JPG reduce its quality?
JPG is lossy, so some data is always removed — but Riducly re-encodes at a balanced quality where the change stays invisible at normal viewing size. You get a much smaller file that looks the same.
Are my files uploaded to a server?
No. Riducly compresses images entirely in your browser, using your device's own processor. Your photos never leave your computer, which keeps the tool private and fast.
What's the difference between JPG and JPEG?
None — JPG and JPEG are two names for the same format. The shorter '.jpg' extension dates back to older systems that allowed only three-letter extensions. Riducly treats them identically.
Will compressing a JPG again make it worse?
Re-compressing a JPG repeatedly can slowly add artefacts, because each pass is lossy. For the best result, compress from the highest-quality original you have rather than an already-compressed copy.
Is there a limit to how many JPGs I can compress?
You can compress multiple files at once for free. Creating a free account unlocks higher limits and parallel, multi-core compression for larger batches.
