Almost every online form has a rule like 'photo must be 600 x 600 pixels and under 100 KB'. When the upload fails, the error message rarely says which part you got wrong, so people try again and again.
Pixels and kilobytes are two different limits
Pixel size is the width and height of the picture. File size is how much storage it takes. You can pass one and fail the other, so check both numbers against the instructions.
Resize first, then compress
Set the exact width and height with the Image Resizer. If the file is still too heavy, run it through the Image Compressor. Doing it in this order keeps the picture sharper than the other way around.
Do not stretch the picture
Keep the aspect ratio locked unless the form demands a different shape. If it does, crop the extra background instead of squashing the face, because a distorted photo can be rejected.
Read the instructions properly
Forms hide their rules in odd places: a small note under the upload button, a PDF guide, or an error message that only appears after you fail. Before you edit anything, write down the format, the pixel size, the maximum file size and whether a plain background is required. Five lines of notes can save ten failed uploads.
Cropping versus resizing
Resizing changes the number of pixels. Cropping cuts away part of the picture. They solve different problems. If the form wants a square and your photo is tall, crop first so the face is centred, then resize to the exact pixels. Resizing a tall photo straight into a square squashes it and looks wrong.
Keep the photo sharp
Always shrink a picture rather than enlarge it. Making a small photo bigger only stretches the pixels and makes it blurry. If you need a larger image than you have, take a new photo with better light and a closer frame instead of forcing the old one.
What about DPI?
Some forms mention 300 DPI or 200 DPI. On a screen, DPI is only a label and does not change how the photo looks. Most portals check the width and height in pixels, while a few also read the DPI value stored in the file. Match the pixel size first, and treat DPI as a secondary detail unless the instructions insist.
A short checklist before you upload
Check the format, the pixel size, the file size and the background colour. Open the file at full size and look at the face and any text. Keep a copy of the final version in a folder named for the application, so that when the next form asks for the same photo you can reuse it in seconds.

What size is a normal passport photo in pixels?
It depends on the country, so always follow the instructions of the office or portal. Many online systems ask for a square image around 600 x 600 pixels.
Why does my photo get rejected even at the right size?
Check the format and the file size too. Many portals accept only JPG, and some reject files over 100 or 200 KB.
