Free Image Tools: Compress, Resize and Convert Photos
Get a photo under 20 KB for an exam form, resize it to exact pixels for a passport-size upload, or switch it from PNG to JPG. These image tools run on your device, so your photos are never uploaded anywhere.
Compress, resize or convert: what's the difference?
Compressing keeps the same width and height but stores the picture more efficiently, which lowers the file size in KB. Resizing changes the number of pixels, for example from 4000 × 3000 down to 600 × 450, which also cuts the size dramatically. Converting changes the format, such as PNG to JPG, which matters when a website accepts only one type.
For most online forms you'll use two of them: resize to the dimensions the form asks for, then compress to the KB limit.
Getting a photo or signature accepted on a government portal
Recruitment and exam sites usually specify three things: format (almost always JPG or JPEG), dimensions (for example 200 × 230 pixels for a photo or 140 × 60 for a signature) and a size range such as 20 KB to 50 KB. Resize first using the exact pixel numbers, then use the target size option in Compress Image. If a site rejects a file that looks right, check that its extension is .jpg and not .jpeg.png or .heic, and convert it if needed.
Picking a format
JPG is best for photographs and is what nearly every form expects. PNG keeps sharp edges and transparent backgrounds, which suits logos, screenshots and signatures on a white background, but the files are larger. WebP gives the smallest files at good quality and is ideal for websites, though some older portals still refuse it.
