Resize Image to 35x45 mm
Upload your photo and instantly resize it to exactly 35x45 mm. Perfect for exam forms, passports, and precise digital requirements.
A 35×45 mm portrait is a common passport and visa photo size in Europe: it is the frame on Germany’s official Foto-Mustertafel and the size the UK government gives for printed passport photos. This browser-based tool scales, center-crops, and converts your picture to 35 mm wide by 45 mm high, which measures 413×531 pixels at 300 DPI print density. The tool outputs a standard JPEG file without transmitting your personal biometric image to any remote server.
The tool center-crops the input to match the 35:45 aspect ratio and runs a compression loop targeting 100 KB or less. Because the automated crop cuts off overflowing borders and the tool cannot clean up or whiten an existing wall, you must use a photo taken directly against a plain light wall with your head centered in the frame.
How it works
1. Step 1 — Upload Photo
Click the drop area labeled “Upload Photo” or drop your file. Use a JPG, PNG or WEBP image and it will open in any modern browser. Photos in Apple’s HEIC format load only when you are browsing in Safari, so convert them to JPG before using another browser.
2. Review Specifications
Examine the preset panel showing 413×531 Pixels, 35×45 mm in Millimeters, 300 DPI Resolution, and the 10–100 KB File Size target range.
3. Resize Photo
Click “Resize Photo”. While processing, the button changes to “Processing...” as it draws the image to canvas and runs a binary search on JPEG quality.
4. Step 2 — Download Result
Check the status banner. If the output file is between 10 KB and 100 KB, it displays “Ready to use”. If the compressed image falls below 10 KB, the tool pads it to 10 KB. If it exceeds 100 KB even at quality 0.1, it saves at quality 0.9 with the status “File size outside target range”. Click “Download” to save the image.

German and UK composition rules for 35x45 mm photos
Germany’s Foto-Mustertafel (the photo sample chart issued with the Federal Ministry of the Interior and published by German missions such as the embassy in San José) sets the geometry for a 35×45 mm photo. For adults, the face must fill 70% to 80% of the photo, which equals 32 mm to 36 mm from the tip of the chin to the top of the head, ignoring the hairstyle. The person must look straight into the camera with a neutral expression, mouth closed and eyes open and clearly visible.
The same chart asks for a plain, light background, ideally neutral grey, with no pattern and no shadows. The UK’s rules for printed passport photos use the same 45 mm high by 35 mm wide frame but give a head height from crown to chin of 29 mm to 34 mm, so the two countries do not use identical proportions. Canada is different again: its passport photos must be 50 mm wide by 70 mm high, so a 35×45 mm file will not work there.
Center-cropping mechanics and background limitations
When an image is processed, the script evaluates the source dimensions against the 35:45 aspect ratio (roughly 7:9). If your original photo is wider than this ratio, the tool trims off equal strips from the left and right sides. If your photo is narrower, it trims the top and bottom. Because this cropping is strictly center-aligned, any face positioned off to one side risks having an ear or the crown of the head cut off. Always center your subject or pre-crop your original photo manually before uploading.
The tool paints a white base on the canvas before drawing the image, which only shows through transparent pixels in files like PNG. It does not replace, lighten, or clean up the background on an ordinary opaque photograph. It does not remove background shadows or adjust room lighting. For a photo that has a chance of meeting these rules, take the picture against a clean, evenly lit plain light surface.
The 100 KB preset ceiling and file size troubleshooting
The 10 KB to 100 KB window is TryDocsy’s own preset, not an official limit; each portal publishes its own file size rules. For JPEG exports, the browser runs up to 15 binary-search compression steps between quality factor 0.1 and 1.0 until the file size measures at or below 100 KB.
If the compressed image falls below 10 KB, the tool adds zero-byte padding inside an extra JPEG APP1 marker to bring the file up to exactly 10 KB, ensuring portals with a minimum file size rule accept it. Conversely, if a highly detailed or noisy image still exceeds 100 KB at quality 0.1, the code falls back to saving at quality 0.9, leaving the file above 100 KB. In that event, the interface warns you with “File size outside target range” instead of “Ready to use”. If this happens, crop closer to the head and shoulders or reduce the resolution of your source file before uploading.
Printing physical photos versus uploading to visa portals
At 300 DPI, 35×45 mm computes to 413.38×531.49 pixels, rounded to 413×531 pixels. If you need physical prints for an embassy appointment, you can place multiple 413×531 pixel copies onto a standard 4×6 inch photo print layout and print them on glossy or matte photographic paper at a photo lab.
Digital uploads often have different rules from prints. The UK’s online passport service, for example, needs a digital photo at least 600 pixels wide and 750 pixels tall and between 50 KB and 10 MB, so this 413×531 pixel output is too small for it. Check whether your application wants prints or an upload, and read that service’s digital requirements.
Frequently asked questions
What is 35x45 mm in pixels at 300 DPI resolution?
At 300 DPI print resolution, 35×45 mm calculates to approximately 413 pixels wide by 531 pixels high.
Can I use this 35x45 mm photo for a Canadian passport?
No. Canada’s passport photo rules require photos 50 mm wide by 70 mm high, which is larger than 35×45 mm.
Does this tool remove shadows or alter my photo background?
No. The resizer does not detect or remove shadows, nor does it whiten existing photo backgrounds. It only paints white under transparent areas. You should shoot your photo against an evenly lit plain light wall.
How big should my face be in a German 35x45 mm passport photo?
The German Foto-Mustertafel says an adult’s face must cover 70% to 80% of the photo, which is 32 mm to 36 mm from chin to the top of the head, not counting the hairstyle.
Why does the result say File size outside target range?
This indicates the image exceeds the 100 KB preset ceiling even at minimum quality 0.1 (files below 10 KB are automatically padded to 10 KB). If it is over 100 KB, crop out extra background clutter or reduce your original file resolution and run the resizer again.
Can I smile in a UK or German passport photo?
No. The UK asks for a plain expression with your mouth closed, and the German chart asks for a neutral expression with the mouth closed.
Can I use this 413x531 pixel file for the UK online passport service?
No. GOV.UK says a digital passport photo must be at least 600 pixels wide and 750 pixels tall, and at least 50 KB. This output is smaller than that.
Does center-cropping risk cutting off my ears or hair?
Yes. The resizer automatically cuts off excess pixels from opposite sides to fit the 35:45 aspect ratio. If your head is not centered in the original capture, crop it yourself before using the tool.
