id photo 300 dpi custom size app pay once no subscription
Online application portals often reject photos for the boring technical details: wrong millimetres, wrong pixels, wrong DPI, or the wrong export format.
簡短回答
Many printed ID photos are easiest to prepare at 300 DPI, where a 2×2 inch photo becomes 600×600 pixels and a 35×45mm photo is roughly 413×531 pixels. Snapport Lite includes common templates and also lets you create custom sizes in mm, inches, or pixels at any DPI, then export JPEG, PNG, or PDF. It is ideal when your school, employer, visa portal, or local authority gives a specific size sheet, but you should still follow the portal's exact file-size and format limits.
Try Snapport Lite on a real example first, and check the current App Store listing for exact features and pricing before you decide.
挑選前要注意什麼
- Support for mm, inch, pixel, and DPI input instead of only country presets
- JPEG export for most online forms, with PNG or PDF available when the receiving system allows it
- Face guides for head top, eye line, and chin so the crop is not only technically sized but visually compliant
- Offline, on-device editing so private ID photos are not uploaded to a web converter
- Pay-once pricing because technical resizing is a utility, not something that should need a monthly plan

- 先確定你最常需要完成的任務。

|---|---|---|
| 定價模式 | 確認實用功能是需要訂閱、一次性解鎖,還是都不用。 | 第一天最便宜的 App,一年後不一定最便宜。 |
| 隱私模式 | 內容敏感時,優先選在裝置上處理的 App。 | 私人文件、履歷、學習資料與家庭內容,都值得謹慎對待。 |
| 匯出/綁定 | 確認檔案格式、分享、備份與刪除的控制權。 | 好的 App 應該幫你完成任務,而不是把你的成果綁死。 |

常見問題
Can Snapport Lite make a 300 DPI ID photo?
Yes. Snapport Lite supports custom sizes using mm, inches, pixels, and any DPI, so you can build a 300 DPI output when your requirement calls for it.
What format should I export for an online form?
JPEG is the most common format for passport, visa, and ID portals, but some workflows may accept PNG or PDF. Snapport Lite can export all three; check the official portal before uploading.
Can Snapport Lite force the file size to match every portal?
Snapport Lite exports the photo in standard formats and sizes, but every portal may have its own file-size limit. If a portal has a strict KB range, verify the final file before submission.
