Compress PNG, JPG, WebP, and AVIF images directly in your browser without losing visible quality. ConverterUp's image compressor is built for designers, developers, and anyone who needs to reduce image file sizes for faster websites, smaller email attachments, or social media uploads. Adjust the quality slider to find the right balance between size and clarity, preview the result in real time, and download the compressed file. Files never leave your device, everything happens client-side using WebAssembly, so the originals stay private and there is no upload queue or wait.
Frequently asked questions
How much can I compress an image without visible quality loss?
JPG and WebP usually compress to 60-80 % quality with no visible difference for photographs. PNG benefits less from quality changes because it is lossless. Convert to WebP or JPG for the largest savings.
Is there a file size limit?
The hard cap is 50 MB per image. Practical performance depends on your device's RAM, but most modern phones and laptops handle 20-30 MB images without issues.
Are my images uploaded to a server?
No. Compression happens entirely inside your browser using WebAssembly. The image bytes never leave your device, and ConverterUp has no upload endpoint at all.
Which formats are supported?
Input: PNG, JPG/JPEG, WebP, AVIF, BMP, TIFF. Output: PNG, JPG, WebP, AVIF. You can also use the compressor as a format converter by changing the output format.
