About this tool
Application forms rarely just say 'upload a photo' — they demand an exact size such as 300 by 300 pixels for a profile picture, 350 by 450 for an admission photograph, or a strict passport dimension. Upload anything else and the form either rejects it or stretches it beyond recognition. This resizer sets the exact width and height you need, in pixels, or scales the whole picture by a percentage when you simply want it smaller. The aspect-ratio lock is on by default, which prevents the classic mistake of a squashed face: change the width and the height follows automatically. Like every tool on this site, resizing is performed by your browser on your own device.
How to use it
- Choose your image and note that its current width and height appear automatically.
- Type the width your form requires; with the lock on, the height adjusts itself to keep proportions correct.
- Alternatively, enter a percentage such as 50 to halve the image without thinking about pixels.
- Pick JPG, PNG or WebP as the output format, then press 'Resize & download' and use the new file.
Where it is used
- Admission and exam forms that specify exact pixel dimensions for photographs and signatures.
- Profile pictures for job portals, university LMS systems and social accounts.
- Passport and ID photographs that must match a stated digital size before printing.
- Website and blog images that need to be smaller so pages load quickly on mobile data.
Tips for a better result
Always start from the largest original you have — enlarging a small image cannot invent detail and will look pixelated. If a form specifies pixels and also a file-size limit in KB, do the resizing here first and then finish with one of our compress tools set to that KB target. For signatures, crop the scan close to the ink before resizing so the signature fills its box and stays bold after the form shrinks it again.
