Supports HEIC, JPG, PNG, WebP, AVIF, TIFF, GIF · Up to 50 files · 50MB max
Reduce image file sizes by 50% to 80% without visible quality loss. The compressor supports JPEG, PNG, WebP, AVIF, TIFF, and GIF, and runs entirely in your browser using the Canvas API and modern codec libraries — your photos never leave your device. A quality slider (1 to 100) lets you trade clarity for size; values between 75 and 85 are the sweet spot for photographs, while 85 to 95 is appropriate for screenshots, charts, and graphics with text. You can drop in up to 50 files at once and download the compressed batch as a single ZIP. The original files are untouched.
Compress before uploading to a website, attaching to an email with a 25MB cap, or publishing to a CMS that imposes per-image limits. JPEG and WebP both use lossy compression and respond well to quality reduction. PNGs containing photographs also benefit from being converted to JPEG or WebP at the same time. Lossless graphics, logos with sharp edges, or screenshots with text are better served by the dedicated Lossless Optimize tool — quality loss is visible faster on hard edges than on photographs.
Drop your images into the upload area
Drag and drop one or many image files, or click the upload area to browse. Files of any supported format can be mixed in the same batch.
Choose a quality value
Use the quality slider. Start at 80 for photographs, 90 for screenshots and UI captures. Lower values produce smaller files at the cost of visible artefacts in smooth gradients.
Preview file-size savings
Each file shows the original size, the compressed size, and the percentage saved. Re-run with a different quality if a particular image is over- or under-compressed.
Download the result
Save individual compressed images, or click 'Download all as ZIP' to get the entire batch in one archive. Originals are never modified.

The compressor supports JPEG, PNG, WebP, AVIF, TIFF, and GIF formats.
Typical results for photos range from 50-80% file size reduction at quality 80. PNGs with flat colors can see reductions exceeding 90%.
Use lossy (this tool) for photographs and detail-rich images where small visual changes are imperceptible. Use the Lossless Optimize tool for logos, screenshots, and any graphic where pixel-perfect output matters.
By default the compressor preserves EXIF data. To strip GPS, camera info, or other metadata, run the dedicated Metadata tool after compression.
