Free online tool to compress JPG, PNG images to 50KB. Aggressively reduce image size to under 50KB for icons, avatars, and strict web upload limits.
JPG, PNG, WebP • Batch Compression
Our aggressive algorithm ensures your image is compressed to strictly under 50KB, even if it means reducing dimensions or quality.
Perfect for optimizing small graphics like website favicons, email signatures, or forum avatars that require tiny file sizes.
Files under 50KB upload instantly on any network condition. Essential for users with slow internet connections.
Some legacy systems, government portals, and email signature tools enforce an extremely low file size limit of 50KB.
Meeting this requirement manually can be frustrating. Our tool handles the heavy lifting, stripping away all unnecessary metadata and optimizing pixels to fit the photo into this tiny space.
Simply upload your image. If the original is large (e.g., 2MB), we might need to significantly reduce its resolution (dimensions) to get it under 50KB.
For best results, we recommend cropping your image to a square or small aspect ratio before uploading if you are creating an avatar.
At 50KB, some quality loss is expected for complex photos. However, for small display sizes (like 100x100 pixels), the image will still look perfectly clear.
We use advanced encoding to keep the visual artifacts to a minimum.
When a system requires a file to be under 50KB, it is often intended for high-frequency loading elements like digital signatures in PDFs or website favicons. At this extreme limit, every single byte of header data matters.
Our 50KB compression engine utilizes advanced chroma subsampling and quantization table optimization. By stripping away non-essential color data that the human eye cannot perceive at small sizes, we allow your digital signature or small logo to remain pixel-perfect while satisfying even the most aggressive firewall upload filters.
Select your photos. JPG and PNG are supported.
The tool automatically targets the <strong>50KB</strong> limit, applying necessary compression.
