Image Tools
Compress, resize, convert and clean up images without installing anything. ToolNova image tools process your files in the browser whenever the tool supports local processing.
Compress Images to a Specific KB Size
For upload forms with a strict file-size limit, use a preset below. These tools aim for the requested maximum size and can reduce image dimensions automatically when quality compression alone is not enough.

Choosing the right image tool
Start with the destination requirement. If a form gives a hard KB limit, use a target-size compressor; if it gives pixel dimensions, resize first. Format conversion is a different task: it changes compatibility, transparency or web efficiency rather than simply making an image smaller.
Keep an original copy before any destructive edit. JPG compression, aggressive resizing and background removal can permanently discard information, while metadata removal intentionally strips descriptive fields. For uploads that contain identity documents or personal photos, prefer the browser-based tools that keep processing on your device.
For best results, crop unnecessary background before compression, use PNG when transparency is required, and check the downloaded file at 100% zoom before submitting it to a portal.
