Compress JPG, PNG and WebP images in your browser. Set a quality level or a target size, preview the result and see exactly how much smaller the file became.
Last updated 5 September 2026
Drag & drop files here, or
JPG, PNG or WebP · up to 100 files, 25 MB each
Drop in one or many JPG, PNG or WebP files.
Move the quality slider or enter a target file size. A live preview shows the effect.
Save each compressed image, or all of them at once.
The image is decoded, drawn to a canvas and re-encoded as JPEG at quality 80. Fine detail your eye ignores is discarded, cutting the file to a fraction of the original while dimensions stay the same.
A photo straight from a phone camera is often 3–6 MB. Compressed to quality 80 it typically drops to 300–800 KB with no visible difference — a 85–90% reduction.
PNG screenshots and graphics compress less because PNG is already lossless. For big savings on those, convert to WebP with our converter instead.
The quality slider is the right tool when you just want "smaller, without looking worse" and don't care about the exact final number of kilobytes — move it until the preview still looks good, then download.
If a form or portal instead demands a precise size range (a maximum, or a maximum and minimum together), switch to target-size mode, or use our dedicated Compress Image to Exact Size tool, which automates the trial and error of hitting that number exactly.
No. Only the file size changes. Use the Image Resizer if you also want fewer pixels — combining both gives the smallest files.
For JPG and WebP it is lossy — you trade a little detail for a much smaller file, and you control how much. For PNG the tool applies lossless optimisation only.
Yes, up to 100 files per batch. Each is processed independently and you can download them together.
No. Compression happens entirely in your browser using a background Web Worker. Nothing is uploaded or stored.
A busy, detailed photo (foliage, crowds, textures) needs more data to describe than a simple one (a plain background, a logo), so the same quality setting produces a larger file for the busier image. This is normal.
Yes — the live preview updates as you move the slider, so you can check the visual trade-off before downloading anything.
JPG, JPEG, PNG and WebP are all accepted as input, and the tool keeps the same format on output unless you choose target-size mode with a different output format.
Very large source files (well over 50 MB) may be slow to process on an older phone, but there is no artificial cap — the practical limit is your device's own memory.
