What our compression engine can do for you.
"Lifesaver! I needed a photo exactly under 50KB for a government exam portal. This hit 48KB instantly without turning the image to mush."
"The fact that it runs offline in the browser is amazing. I don't have to worry about uploading my ID cards to sketchy websites anymore."
"Clean, premium UI and it does exactly what it says. I typed in 1MB for my high-res banner and it gave me a 980KB file. Perfect precision."
"Lifesaver! I needed a photo exactly under 50KB for a government exam portal. This hit 48KB instantly without turning the image to mush."

Our algorithm usually achieves an accuracy of about 90% to 98%. Because image compression is mathematically complex and depends on colors/details, hitting the exact byte size is impossible, but we guarantee it will fall just under your target requirement so it is accepted by upload portals.
If you upload a massive 4K image and request a 20KB target, simply lowering the JPEG quality to 1% is not enough. When the engine realizes the file is still too big at the lowest quality, it smartly scales down the physical dimensions (pixels) of the image to ensure you meet your strict MB/KB limit.
No. 100% of the processing happens directly inside your web browser using HTML5 Canvas APIs. Your files are never sent to our servers, ensuring absolute privacy for sensitive documents like signatures, passports, and ID cards.
Because PNG is a lossless format, adjusting "quality" doesn't reduce file size significantly. To achieve exact target sizes, our tool automatically converts PNG files to high-quality JPEG (which removes transparency by adding a white background) before compressing.
