How It Works
Compress images in three simple steps
Upload Your Images
Drop JPG, PNG, or WebP images onto the upload area. You can upload up to 20 images at once with a combined size of 50 MB on the free plan. All three formats can be mixed in a single batch — each is compressed with the optimal algorithm for its format.
Choose Compression Level
Select Light (~30% reduction), Medium (~60%), Strong (~80%), or Extreme (~90%). Medium is the sweet spot for web images — noticeably smaller with no visible quality difference at normal viewing sizes. Optionally choose WebP output for even smaller files.
Download Compressed Files
Compressed files are delivered with the same names as your originals plus "-compressed". Multiple images are packaged into a ZIP for one-click download. Results show original vs compressed file sizes and the percentage saved.
Image Compression Features
Smart compression — smaller files without the visible quality hit
Up to 90% Size Reduction
Smart compression analyses each image and applies the optimal compression parameters for that specific image's content, colour complexity, and texture. Flat areas are compressed more aggressively; detail areas are protected. This produces significantly smaller files than blunt quality-slider tools.
JPG, PNG, and WebP
Each format is compressed with its own algorithm: JPG uses perceptual quality with chroma subsampling; PNG uses lossless deflate optimisation with palette reduction; WebP uses both lossy and lossless modes depending on the selected level. You can also convert to WebP at compression time for the smallest possible output.
Batch Compress 20 Images
Upload up to 20 images in one batch and compress them all simultaneously. The same compression settings are applied to each image, and all outputs are packaged into a ZIP archive. Ideal for compressing product image galleries, blog post images, or a folder of photos before uploading to a website.
Progressive JPEG Encoding
Progressive JPEG encodes images in multiple passes — the browser renders a blurry version first, then gradually sharpens it as more data loads. This gives a better perceived loading experience on slow connections and typically produces slightly smaller files than baseline JPEG at the same quality setting.
EXIF Strip
EXIF metadata (camera settings, GPS location, timestamps) embedded in JPG files can add 5–30 KB per image. Stripping EXIF is enabled by default and has no visible effect on the image — it reduces file size and removes potentially private location data from photos you share or publish online.
100% Private & Secure
All uploads are encrypted with TLS 1.3. Images are processed in isolated server containers and permanently deleted within 24 hours. No watermarks are added to compressed images. We never view, store, or share your files beyond the active processing session.

Frequently Asked Questions
At Light and Medium compression levels, the quality difference is virtually invisible on screens — most viewers cannot tell the difference between an uncompressed image and one compressed at 80% quality. At Strong and Extreme levels, very close inspection or zooming in may reveal subtle softening in fine detail areas. For web use, Medium compression is almost always the right choice — browsers and screens cannot display the additional quality anyway.
WebP is the best choice for web images in 2024 — it outperforms both JPG and PNG on file size while being supported by 97%+ of browsers. JPG is the second-best for photographs where file size matters more than transparency. PNG is best for images requiring transparency, sharp edges (logos, diagrams), or pixel-perfect fidelity — but at the cost of larger files. When in doubt, convert to WebP during compression for the smallest output that covers all use cases.
For JPG: yes — each re-compression at lossy quality introduces additional artefacts (generation loss). To avoid this, always compress from the original source file, not from a previously compressed copy. For PNG: no — PNG compression is always lossless, so re-compressing a PNG never degrades pixel quality regardless of how many times it is done. For WebP at quality 100 (lossless mode): no; at lossy quality: yes, same as JPG.
EXIF metadata is information embedded in JPG files by cameras and smartphones — including GPS coordinates, device model, date/time, camera settings, and sometimes software used. Stripping it reduces file size by 5–30 KB per image, and more importantly, removes the GPS location data that could reveal where a photo was taken. This is especially important for photos shared on public websites or social media where you don't want location information to be publicly accessible.
Typical results: smartphone photos (3–8 MB) can compress to 300–800 KB at Medium quality — a 70–90% reduction. Screenshots and graphics with large flat areas compress most aggressively. Already-compressed JPEGs (e.g. downloaded from a website) have less room to compress further. Converting JPG or PNG to WebP at Medium quality typically achieves 40–70% reduction vs the input. Results vary by image content — images with lots of visual complexity compress less than simple ones.
