A file compressor shrinks the size of an image or file so it loads faster on the web, fits inside an email attachment limit, or takes less storage. This tool supports PNG, JPG, and WebP image compression, both lossy and lossless. Lossy compression trades a small amount of visual quality for a much smaller file, ideal for web and email. Lossless keeps every pixel intact for archival, print, or when transparency matters.
Drag a PNG, JPG, or WebP into the upload area, or click to browse. You can compress multiple files in one batch.
Pick lossy for the smallest size at web-acceptable quality, or lossless to preserve every pixel. For photos, lossy JPG or WebP usually wins. For logos and screenshots, lossless PNG keeps text crisp.
Slide between high compression and high quality. A quality of 75 to 85 is the sweet spot for most web images.
Check the before and after to confirm the image still looks good at the new size. Most photos shrink 60 to 80 percent with no visible difference.
Save the smaller file and use it for your website, email, or upload destination. Original is never overwritten.
Lossy compression removes some detail the eye barely notices, so quality drops slightly but file size drops a lot. Lossless compression keeps quality identical and shrinks the file by removing redundant data only.
JPG is best for photos and uses lossy compression. PNG keeps transparency and lossless detail, ideal for logos and UI. WebP is a newer format that compresses better than both and is supported by all modern browsers.
The compressor handles typical web and email images up to around 50 MB per file. For very large images, resize the dimensions first, then compress.
Compression runs in your browser when possible, so files do not leave your device for most formats. Nothing is stored on our end after you close the tab.
Photos typically drop 60 to 80 percent in lossy mode at quality 80. PNGs with flat colors and screenshots can drop 30 to 50 percent in lossless mode. Results depend on the source image.
