When should I use this instead of a preset?

Whenever your form states a size that no preset matches, or when a portal has changed its specification since a preset was last reviewed. The upload screen is always the authority.

How do I convert centimetres to pixels?

Multiply by about 118 for 300 DPI, or by about 79 for 200 DPI. A 3.5 x 4.5 cm photo at 300 DPI is roughly 413 x 531 pixels. If the portal states pixels, use its figure rather than converting.

Custom size resizer

Resize and compress an image to any pixel dimensions and file size band you specify. Use this when your form asks for a size no preset covers.

What this form requires

Official rules and our own recommendations are labelled separately, so you can tell which is which.

DocuFix recommendationEnter the width, height and file size band your form asks for. Nothing here is a claim about any authority.
DocuFix recommendationWhere your form states both a minimum and a maximum file size, enter both. The encoder targets the band rather than only staying under the ceiling.

What causes rejections

Entering the printed size in centimetres where the portal wants pixels. Multiply centimetres by 118 for 300 DPI, or read the pixel figure directly off the upload screen.
Compressing below a stated minimum file size.

What this tool can and cannot check

Checked automatically

Exact pixel dimensions
File size under 200 KB
JPEG output in the sRGB colour space
That the file is a real image, not a renamed HEIC or PDF

Judged by a person or the portal

Whether your expression is neutral
Whether hair or a head covering obscures your face
Whether the photo is recent enough
Head height, which the crop guide targets but does not measure
Whether the photograph is genuinely of you

Passing every automated check here does not mean your application will be accepted. It means the file will not fail for a technical reason.

How your image is handled

Your file is read into this page, decoded, drawn onto a canvas at the target size and re-encoded. Every step runs on your device. No network request carries the image, so nothing is stored on our side and nothing can be recovered from us later.

Re-encoding through a canvas also converts the file to the sRGB colour space and strips the original EXIF metadata, including any location tag your camera wrote into it.
