Photo and Signature Resizer – Resize Image to 20 KB, 50 KB or Any Size
Almost every online form for a government job or an entrance exam asks for a passport size photo and a signature in a fixed size. The file must be a JPG, the width and height must match what is written, and the file size has to stay between two numbers, for example 20 KB and 50 KB. A picture taken on a normal phone is two to five MB, so the upload simply fails.
This photo and signature resizer brings your picture down to the size your form wants in a few seconds. You choose the width, height and the maximum KB, and the tool finds the best quality that still fits. Everything happens inside your own browser, so your photo is never sent to our server.
How to use the Photo & Signature Resizer
- Tap the box and choose your photo or your signature from the gallery, or click a fresh one with the camera.
- Pick a ready-made size from the list, or type your own width and height. If the notice gives the size in centimetres, change the unit to cm and keep 300 dots per inch unless the notice says something else.
- Type the maximum file size in KB, for example 50. If the notice also gives a minimum size, type that in the minimum box. Leave 0 when there is no limit.
- Press "Resize my picture", look at the preview, and tap the download button. Upload that file on the form.
How to decide the size to type
Always take the size from the notification or from the "photo upload" page of the form, because it changes from exam to exam. Three things are normally written there: the type of file (almost always JPG or JPEG), the dimensions, and the file size. The dimensions can be in pixels, like 200 x 230, or in centimetres, like 3.5 cm x 4.5 cm. When it is in centimetres, choose cm in the unit box. The tool converts it into pixels using the dots per inch value, which is 300 by default.
The ready-made sizes in the list are only common examples. They are there to save your time, not to replace the notice. If your form asks for something different, simply type your own numbers.
Choosing "crop" or "keep the whole picture"
For a face photo, the best choice is Crop to fill the size. The tool trims the extra part from the edges and keeps the face in the middle, so the face does not look squeezed. For a signature, choose Keep the whole picture, so that no part of the signature is cut. "Stretch" is there for rare cases, but it can make a face look thin or fat, so avoid it for photographs.
What makes a photo get rejected
- Wrong file type. A PNG, a screenshot or a HEIC photo from an iPhone may not be accepted. Choose JPG in this tool.
- File too big or too small. Some forms also refuse a file that is below the minimum size. If that happens, increase the width and height a little.
- Dark or blurred picture. Lowering the KB reduces the quality, so start from a bright and sharp picture.
- Old photo or cap and goggles. Many forms ask for a recent photo with a plain light background and the full face visible. Read the instructions on the form once.
- Signature on coloured paper. Sign with a black or blue pen on plain white paper and take the picture in daylight.
Tips for a clean photo and signature
Stand in front of a plain wall, near a window, and ask someone to click the photo at your face level. Keep the face about three-fourths of the frame. For the signature, sign inside a rectangle drawn on white paper, take a close picture, and then crop. Do the same signature that you will use at the exam centre, because the signature is checked there.
If you have only a photo-studio CD or a very old scan, it is better to click a new one on your phone than to enlarge a small picture, because enlarging a small picture makes it blurry.
Frequently asked questions
Is this photo resizer free?
Yes. It is free, and there is no login and no watermark on the picture.
Is my photo safe? Does it go to your server?
No. The resizing runs inside your own browser on your phone or computer. The picture is not uploaded, so nobody else can see it.
The file is still above my KB limit. What should I do?
Use a smaller width and height. A picture with fewer pixels needs fewer KB. Also check that you have chosen JPG, because a PNG cannot be reduced to a size limit.
Why does my picture look a little soft after resizing to 20 KB?
A very small file keeps less detail. To keep the face clear, start with a bright, sharp picture and do not make the pixel size bigger than the form asks.
Can I use this for a signature or a thumb impression?
Yes. Choose the picture, choose "Keep the whole picture", type the size from your notice and download the JPG.
Can I use it on mobile?
Yes. The page is made for phones. You can pick a photo from the gallery or click one with the camera.
