About our Image Tools

Most government portals, job sites and college forms ask for photos under a fixed size, such as 50 KB or 200 KB. The Image Compressor lets you type that target in KB and tells you honestly if the size cannot be reached without shrinking the picture. When the dimensions are the problem, the Resizer & Cropper sets exact pixel sizes or percentages, with an aspect-ratio lock, crop handles, rotation and flipping.

The Image Converter re-encodes pictures between JPG, PNG and WebP using real pixel rendering, handles transparent backgrounds with a colour of your choice, and can convert many files at once and download them as one ZIP. If a photo contains text you need to copy, the Image to Text (OCR) tool reads English and Hindi, and you will find it in our Text & Code tools.

Frequently Asked Questions

Does ToolKhoj upload my photos to compress or resize them?
No. Compression, resizing, cropping and conversion happen in your browser using your device's memory, so the pictures stay on your phone or computer.
Will compressing a photo reduce its quality?
JPEG and WebP compression is lossy, so some detail is traded for a smaller file. You control the quality slider or a target size in KB, and a side-by-side preview shows the result before you download.
Which image formats can I convert between?
The Image Converter supports JPG, PNG and WebP in any direction. When you convert a transparent PNG to JPG you can choose the background colour that fills the transparent area.
