Targeted Compression
If you request a 100 KB limit, the engine automatically calculates the required image quality and scales down the resolution proportionally if the image is exceptionally large.

How the smart sizing works
Getting a photo under a strict file limit used to mean guessing quality sliders. This tool handles the maths for you.
Format Conversion
Switch freely between JPEG, PNG, and WebP. Need a transparent background? Choose PNG. Need the smallest possible file? WebP often outperforms JPEG while retaining better detail.
100% Private
Unlike server-based converters, your images are processed by your own browser using HTML5 Canvas. Your photos are never uploaded to our servers, ensuring absolute privacy.
Questions
Frequently asked
Are my images uploaded to a server?
No. The file is opened, resized, converted, and saved entirely inside your browser tab. Nothing is transmitted over the internet, so your private documents and photos stay perfectly secure.
How does it reach the exact target size?
The tool acts like a smart search algorithm. It tests compression levels and, if necessary, slightly scales the physical pixel dimensions of the image until it safely tucks in under your required KB limit.
Which format should I choose?
Use JPEG for standard photographs, especially for portal uploads. Use PNG if your image has text, sharp graphics, or requires a transparent background. Use WebP for modern web usage, as it offers the highest quality at the lowest file size.
Why did it change my image dimensions?
If an image is physically huge (e.g., 4000x3000 pixels) and you demand a tiny file size (e.g., 50 KB), lowering the quality alone results in blocky artifacts. In those cases, the tool automatically resizes the image down to a sensible resolution so it stays clear while meeting your limit.
