How it works

A compact workflow from input to download.

1

Add your photo

Drop in a JPG, PNG, WebP, or iPhone HEIC file. The original dimensions are read and shown so you know your starting point.

2

Enter the required dimensions

Type the width and height the form specifies. Unlock the aspect ratio when a form demands a fixed size that differs from your photo's shape.

3

Download and submit

The resized image is produced locally. If the form also caps file size, compress it to the required KB afterwards.

Tool details

Practical capabilities and safeguards built into this workflow.

Type the exact numbers

Forms specify dimensions in pixels, not vague sizes. Enter the precise width and height rather than dragging a slider and hoping.

Aspect-ratio lock, on or off

Keep proportions when scaling a correctly framed photo, or release the lock when a form mandates a specific non-matching ratio.

Identity photos stay local

ID photographs are sensitive personal data. This tool never uploads them — resizing happens entirely in your browser.

Handles signatures too

Many applications require a separate signature image at its own dimensions. The same resizer covers both.

Pairs with size compression

Forms usually cap both pixels and kilobytes. Resize here, then compress to the KB limit as a second step.

No signup, no watermark

No account, no export cap, and nothing stamped onto a document you are about to submit officially.

Frequently asked questions

What size photo is needed for an Aadhaar card?
Aadhaar enrolment photographs are captured at the centre rather than uploaded, but online update portals typically ask for a photo in the 35×45mm range, which is 413×531 pixels at 300 DPI, and often cap the file at a specific kilobyte limit. Always use the exact numbers printed on the portal you are using.
What is the photo size for a PAN card application?
PAN applications generally specify a 3.5×2.5cm photograph. Submitted digitally that is commonly around 413×295 pixels at 300 DPI, with a small file-size cap. Because these figures change between forms and providers, check the instructions on your specific application rather than relying on a remembered value.
How do I convert millimetres to pixels for an ID photo?
Multiply the measurement in inches by the required DPI. A 35×45mm photo is 1.38×1.77 inches, so at 300 DPI it is roughly 413×531 pixels. At 600 DPI it doubles to 827×1063. If a form gives you millimetres and a DPI, that calculation is all you need.
Should I resize or crop first?
Crop first, resize second. Cropping sets the composition and aspect ratio; resizing sets the pixel dimensions. Doing it the other way round means you resize data you are about to throw away, and you may end up with the wrong ratio.
Will resizing make my ID photo blurry?
Scaling down is generally safe and often sharpens perceived detail. Scaling up cannot invent detail that was not captured, so an upscaled small photo will look soft. Always start from the largest original you have.
Is my photo uploaded to a server?
No. The resizer runs in your browser using the Canvas API, so your identity photograph is never transmitted, stored, or logged anywhere.
What if the form also has a file-size limit?
Resize to the required dimensions here first, then use the passport photo compressor to hit the exact kilobyte target. Doing it in that order preserves the most quality, because reducing pixels removes far more data than reducing JPEG quality.

ID Photo Dimensions: Millimetres, Pixels, and DPI

Almost every ID photo specification is written in millimetres, because the standards predate online applications and assume a printed photograph. Upload forms, however, validate pixels. Converting between the two requires one extra number — the DPI, or dots per inch, that the form assumes. Get that conversion right and most rejections disappear.

Doing the conversion

Divide millimetres by 25.4 to get inches, then multiply by the DPI. The common 35×45mm ID photo becomes 1.38×1.77 inches, which at 300 DPI is 413×531 pixels and at 600 DPI is 827×1063. Where a form states only pixels, use those numbers directly and ignore DPI entirely — DPI is metadata that matters for printing, not for how many pixels an image contains. An image is only ever as detailed as its pixel count.

Why the aspect-ratio lock matters

ID photos are usually taller than they are wide, at roughly a 7:9 ratio for the 35×45mm standard. If your source photo is a normal 3:4 or 16:9 camera image, scaling it to ID dimensions with the ratio locked will not produce the required shape. The correct sequence is to crop to the target ratio first — which lets you control what gets cut — and then resize with the lock on. Resizing with the lock off instead stretches the image, which distorts facial proportions and is a common cause of rejection.

Composition rules that resizing cannot fix

Most ID standards also govern content: a plain light background, the head occupying between 70 and 80% of the frame height, a neutral expression with both eyes open, even lighting with no shadow behind the head, and no glare on glasses. No amount of resizing corrects any of these. Check the composition rules before you start, because a perfectly sized photo that breaks them is still rejected.

Order of operations for a clean submission

Work in this sequence: shoot or select the highest-quality original available, crop to the required aspect ratio, resize to the specified pixel dimensions, then compress to the file-size limit if one applies. Each step narrows the file, so running them out of order discards quality you cannot recover. Use the cropper for step two and the passport photo compressor for step four.
