Upload up to 20 images and compress them all at once with adjustable quality. See the file size savings for each image. Download individually. Free, no watermark, all processing in your browser.
Choosing the right quality level balances file size reduction against visual quality. Here is what each quality range delivers.
Minimal compression. File size reduction is small (10-20%). Use when absolute image fidelity is required — like professional photography archives or print preparation.
Excellent quality with good compression. File size reduces by 50-65%. Nearly indistinguishable from the original. The recommended setting for most web images and social media.
Good quality with strong compression. File size reduces by 70-80%. Some compression artifacts may appear in highly detailed areas. Ideal for website thumbnails and previews.
Moderate quality with heavy compression. File size reduces by 85-90%. Visible artifacts but acceptable for email previews, loading placeholders, and low-bandwidth contexts.
WebP format achieves 25-35% better compression than JPG at equivalent quality. Use WebP for website images where page load speed matters. Supported by all modern browsers.
PNG compression is lossless — no quality loss at any setting. Quality slider affects only JPG and WebP. PNG is always recommended for logos, text, screenshots, and graphics.
Click the upload zone or drag and drop multiple images at once. JPG, PNG, and WebP files are supported. Upload up to 20 images per batch.
Adjust the quality slider — 80% is recommended for most uses. See each image's compressed size and savings percentage in real time.
Click Download under each image to save it individually, or use Download All to save all compressed images at once.
You can upload and compress up to 20 images per session. All compression happens in your browser so very large batches (many 4K images) may be slow on older or less powerful devices.
No. All compression happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device and are never stored, shared, or accessible to anyone else.
80% quality is the recommended default for most web images — it reduces file size by 70-80% with nearly invisible quality loss. For professional photography, use 90%. For thumbnails and previews, 70% is fine.
Yes. PNG compression is lossless — the quality slider does not apply to PNG output. PNG files are compressed using lossless deflate compression, typically reducing size by 10-30% compared to unoptimized PNGs. For larger reductions, consider converting PNGs to WebP or JPG.
Yes. The quality slider applies to all images in the current batch. If you want different quality settings for different images, process them in separate batches.
No. The downloaded images contain only your original compressed photo — no watermark, no logo, no attribution of any kind.
