What this tool does
Reduce photo file size to an exact KB target. Optionally resize/crop and export as JPG, PNG or WEBP. Zero‑Upload keeps processing on your device.
Perfect for online forms, job portals, email limits, and faster websites. Batch multiple images and download a ZIP.
How do I reduce an image to a specific KB? ›
Upload your image, choose a target size (KB) using the slider or presets, and click Compress. The tool iteratively adjusts quality to hit your target closely.
Will my photos be uploaded to a server? ›
With Zero‑Upload enabled, compression happens locally in your browser. Nothing is sent unless you disable it or use a server-only feature.
Can I change width and height? ›
Yes. Set optional width/height and lock aspect ratio if needed. The tool shows suggestions and an upscaling warning when applicable.
