Crop and compress to 35 × 45 mm
Three steps. Crop to the 7:9 portrait ratio, hit the KB ceiling, export as JPG.
Upload your photo
Drop a JPG, PNG, WebP, or iPhone HEIC onto Sukat’s drop zone. HEIC is decoded directly — no separate conversion step.
Crop to 35 × 45 mm and clean the background
Click Crop, use the on-canvas dimension hint to frame the 35:45 portrait ratio (chin to crown should sit between 35–40 mm). If the background isn’t plain white, click Remove Background — Sukat segments you with a local AI model and offers a colour picker. Pick pure white.
Set 413 px width and the KB cap
Set Target Width to 413 (which yields 413 × 531 px at 300 DPI — exactly 35 × 45 mm), output format to JPEG, and Maximum File Size to your portal’s cap (200 KB for Indian Passport Seva, 500 KB for Schengen, etc.). Click Convert & Download.
Which forms accept the 35 × 45 mm photo
35 × 45 mm is the ICAO biometric-document baseline — the size every country outside the US has converged on for passports, visas and most photo IDs.
- Indian Passport Seva — fresh and re-issue applications via passportindia.gov.in. The portal accepts 413 × 531 px JPG between 20–300 KB.
- Schengen visa applications — France, Germany, Spain, Italy, the Netherlands, and all other Schengen-area embassies. The pixel target is the same; the KB cap is typically under 500 KB.
- UK passport renewal — HM Passport Office accepts 35 × 45 mm at a minimum of 600 × 750 px (its own slightly larger pixel target), 50 KB to 10 MB.
- Australia and New Zealand visa applications — Department of Home Affairs and INZ both use the 35 × 45 mm standard.
- Philippines DFA passport — the appointment system requires a 35 × 45 mm JPG under 300 KB for online uploads.
- Japan and Korea visa applications — consulate portals across most embassies converge on the same 35 × 45 mm spec, typically under 240 KB.
- ICAO biometric documents broadly — the 35 × 45 mm portrait, face occupying 70–80% of frame height, plain light background, is the Document 9303 baseline most countries map to.
Built for the 35 × 45 mm spec specifically
A passport photo isn’t just a KB target — it’s pixel dimensions, aspect ratio, background, and KB at the same time. Most compressors only solve one of those.
Hits 413 × 531 px and the KB cap together
Sukat resizes to exactly 413 × 531 px (35 × 45 mm at 300 DPI), then binary-searches the JPEG quality scale for the highest setting that fits under the ceiling. One pass, both constraints satisfied. Generic resizers force you to chain a crop tool, a resize tool, and a compressor across three different sites.
Portrait-aspect crop tool built in
The 7:9 portrait ratio is unusual — most editors only ship 1:1, 4:3 and 16:9 presets. Use Sukat’s Crop tool with the on-canvas dimension hint to frame the 35:45 portrait ratio before you compress, and the chin-to-crown marker keeps the face inside the 70–80% band most portals require.
HEIC input handled, JPG output guaranteed
iPhone selfies arrive as HEIC. Sukat decodes them in-browser and re-encodes to JPG — the only output format every passport portal accepts. No separate convert-to-JPG step, no silent failures.
Background replacement, white by default
Click Remove Background. Sukat segments you with a local AI model, opens a colour picker, and lets you drop pure white behind the subject — the colour every 35 × 45 mm portal wants.
Privacy-grade, like the document itself
A passport photo is identity-grade material. Sukat runs entirely in your browser via the Canvas API and the WebAssembly segmentation model. The photo never reaches a server — switch to airplane mode after the page loads to verify.
