Image Compressor
Re-encode a photo locally, compare its actual file size, and download a fresh JPEG, PNG, or WebP. Your image stays in your browser.
Or drop a file here / paste an image. JPEG, PNG, WebP · 50 MiB, 20 MP, 8192 px per edge.
Same dimensions.
A fresh export.
Choose an image, generate a new file, then compare the preview and download it.
No image selected.
Generate an output to see its actual size.
Choose a local image to begin.
Background processing when supported.
The preview fits this panel. Actual output details appear after encoding. Changing a setting discards the previous output.
LESS TO CARRY
Keep the frame.
Find the size.
Compare real files.
Choose an image, set the output format and quality, then compress. The result shows both file sizes in bytes, the percentage change, and the oriented dimensions. If the new file is larger, the tool says so. Try lower JPEG or WebP quality, or use the image resizer first when the destination needs fewer pixels.
Compression depends on the picture.
JPEG suits photographs and fills transparent pixels with your chosen background color. WebP retains transparency when your browser can export it. PNG is lossless for the decoded pixels and ignores the quality slider; this tool re-encodes PNG rather than optimizing its palette or searching compression settings. Smaller output is never guaranteed. Your original file remains untouched.
A fresh export has limits.
The browser applies image orientation and renders to an sRGB canvas. Original EXIF, GPS, text, color-profile, and animation data are not copied. Animated inputs become one browser-selected still frame, and the encoder may add its own technical metadata. This is not a calibrated color workflow.
JPEG, PNG, and WebP input only. Maximum 50 MiB, 20 MP, 8192 px per edge. Headers are checked within the first 1 MiB, then decoded dimensions are validated. Unusual or damaged files may need a standard re-export. Without worker image support, source and output are limited to 4 MP. Clear, cancel, replace the file, or leave the page to release local work and previews.
