Everything you need to prepare a photo & signature

Online application portals are strict about images: your photograph and signature must be a precise size in pixels and a specific file weight in KB, or the form is rejected. This image toolkit covers the whole job — set exact dimensions with the Image Resizer, hit a KB limit with the Image Compressor (you can even compress to a specific 50 KB), create a clean white-background photo with the Passport Photo Maker, and prepare your signature with Signature Resize.

Beyond form prep you can remove a photo background, crop to any ratio, convert between PNG, JPG and WebP, combine a photo and signature, join several photos, and resize for social media. Need a head start for a specific format? Try the ready-made SSC CGL and UPSC photo presets. Every tool runs locally, so your files never leave your device.

Frequently asked questions

Which image tool do I need for an online form?
Most online forms need a passport-style photo and a signature at exact pixel sizes and KB limits. Use the Image Resizer to set the dimensions, the Image Compressor to hit the KB target (often 20–50 KB), the Passport Photo Maker for a white background, and Signature Resize for the signature.
How do I compress a photo to an exact KB?
Open the Image Compressor, upload your photo, and enter the target size (for example 50 KB). It reduces the file to that limit while keeping the best possible quality — all in your browser.
Are these image tools really free and private?
Yes. Every image tool is completely free with no sign-up or watermark, and all editing happens inside your browser, so your photos and signatures are never uploaded to any server.
What image formats are supported?
The tools work with common formats like JPG, PNG and WebP. The Image Converter lets you switch between PNG, JPG and WebP, and most tools export a JPG or PNG suitable for online application portals.
