Online forms rarely ask for just "a photo". They ask for one 200 pixels wide, or 3.5 × 4.5 cm, or between 20 and 50 KB. This tool resizes JPG, PNG, WebP, GIF and BMP pictures to the exact width and height you type, and can keep the file within a range in KB at the same time.
It works on one photo or a whole batch, and the pictures are resized by your own browser, never uploaded. That matters when the photo is of you, your ID card or your child.
How to resize an image
- Choose one or more pictures, or drop them onto the page.
- Under Size in, pick Pixels, %, cm, mm or inch, then type the Width and Height. Leave Height empty to keep the proportions, or choose a Form preset if your form is listed.
- With both sides set, choose Fit inside, Crop, Border or Stretch.
- If the form gives a file size, type it into Keep under (KB) and, for a minimum, At least (KB).
- Select "Resize image" and download. The notes show the old and new size of each picture.
Fit inside, Crop, Border or Stretch
- Fit inside keeps the proportions within your width and height, so one side may come out smaller.
- Crop gives exactly that size and trims the edges. Usually right for a photo on a form.
- Border gives exactly that size by adding bands of a colour you choose, so nothing is cut off.
- Stretch forces the exact size and changes the proportions, which makes faces look wider or thinner.
Centimetres, dpi and pixels
A size in centimetres only becomes pixels at a resolution. At 300 dpi, 3.5 × 4.5 cm is 413 × 531 pixels; at 200 dpi it is 276 × 354. Choose the Resolution your form mentions; it is also written into JPEG and PNG files, so they print at the size you meant.
Width and height are not the same as file size: two photos of 200 × 230 pixels can differ in KB because of their detail. Keep under (KB) lowers the quality until the file fits, without changing the pixel size you chose. If even the lowest quality is too big, you are asked for a smaller size or a higher limit.
When a form wants a minimum size
Some forms reject files that are too small. At least (KB) pads a JPEG or PNG with an invisible comment until it reaches the minimum, without changing the picture; WebP can't be padded. Portals count a KB as 1000 or 1024 bytes, so the maximum is taken as 1000 bytes and the minimum as 1024, and the file passes either way.
Frequently asked questions
How do I resize a photo for an SSC or other exam form?
Take the width, height and KB range from the exam notification. Type the size here, choose Crop, save as JPEG, and enter the range in Keep under (KB) and At least (KB). Check your form's notification for the exact size each time, as it can change.
Can I reduce an image to 20 KB without changing its dimensions?
Yes. Choose % and 100, set Save as to JPEG, and type 20 into Keep under (KB). If the pixel size doesn't matter, Compress image can also reduce the pixels when it must.
Will making a small photo bigger improve it?
No. Enlarging can't add detail, so a small picture made bigger looks soft, and the notes warn you. Start from the largest original you have.
Are my photos uploaded?
No. They are read, resized and saved by your browser on your own device. Add as many as you like and download them together as a ZIP.
