Government portals, visa applications, and job sites often require photos with exact pixel dimensions and file size limits. A typical rejection reason is "file too large" or "wrong dimensions" even when the photo itself looks fine.
Common Requirements
| Document | Dimensions | Max File Size |
|---|---|---|
| Passport photo (online) | 600×600 to 1200×1200 px | 200–500 KB |
| Korean ID photo | 413×531 px | 500 KB |
| Visa application | 600×600 px | 240 KB |
| Job portal profile | 300×400 px | 100–200 KB |
Step-by-Step Workflow
- Resize first: Open Image Resize. Set the exact width and height required. Lock aspect ratio if the portal allows slight variation.
- Compress to target size: Open Image Compress. Set the maximum file size (e.g., 200 KB). The tool adjusts quality automatically.
- Convert format if needed: Some portals only accept JPG. Use Image Converter to switch from PNG or WebP.
- Verify: Check the final file's dimensions and size before uploading.
Tips
- Always resize before compressing. Smaller pixel dimensions make it much easier to hit a tight file size limit.
- If the result looks blurry, try a slightly higher target size and check if the portal accepts it.
- Save the original photo separately. Once compressed, quality cannot be restored.
Why Browser-Based Tools Work Well Here
Official documents are sensitive. Using a browser-based tool means your photo stays on your device and is never uploaded to a third-party server. This matters for passport photos, ID cards, and personal documents.
