Fitframe – a browser‑only tool that makes passport photos meet visa portal upload rules

说明与用途

Fitframe 是一个仅在浏览器中运行的工具，自动裁剪、缩放并填充护照照片，以满足签证门户的上传规则，处理尺寸、DPI、文件大小限制和 EXIF 删除。

问题

Government visa portals require passport photos to meet strict size, dimension, and file‑size limits, but no consumer tool handles all variations, especially minimum file‑size floors and EXIF stripping.

结果

Fitframe consistently produces passport photos that satisfy diverse visa portal requirements, handling dimension, DPI, file‑size floors, and metadata stripping in a single click, all without uploading the photo to a server.

工作流

• 1. Drop, paste, or pick a photo; the tool reads rotation metadata correctly.
• 2. Enter portal rules: width/height (px/mm/inches with DPI), min/max file size (KB), format, or use a preset.
• 3. Drag/zoom the photo inside the target‑proportion frame (or pad with white).
• 4. Click "Make it fit" – the tool resizes, tunes JPEG quality, and pads to meet size limits.
• 5. Receive pass/fail feedback for each rule and download the compliant image.
• 6. (Optional) Edit preset rules or report unsupported rules to the author.

证据

Fitframe runs entirely in the browser: canvas for the crop and resize, toBlob for encoding, a bit of byte‑level work for the padding. There is no backend.

来源

Fitframe’s approach: first it tries raising the quality. If the file is still under the floor, it inserts a JPEG comment segment (or a PNG text chunk) filled with whitespace to reach the minimum.
