How to convert photos to HD in bulk
- Tap Choose multiple product images and select your photos.
- Pick a Minimum output resolution: Full HD · 1920 px, 2K / QHD · 2560 px or 4K · 3840 px long edge.
- Check the table: it lists the input and output size of the first five photos.
- Tap Process and download ZIP.
The ZIP holds one JPG per photo, named after the original with a number added, plus outcome-report.csv listing any file that failed. More photo tools are on the tools page.
What size each photo comes out
The long edge is set to the size you pick and the short edge follows, so nothing is cropped or stretched. Worked from the tool’s formula (22 Oct 2026):
| Your photo | Full HD (1920) | 2K (2560) | 4K (3840) |
|---|---|---|---|
| 1200 × 1600 (portrait) | 1440 × 1920 | 1920 × 2560 | 2880 × 3840 |
| 800 × 800 (square) | 1920 × 1920 | 2560 × 2560 | 3840 × 3840 |
| 4000 × 3000 (camera) | 4000 × 3000 (unchanged) | 4000 × 3000 (unchanged) | 4000 × 3000 (4000 is already over 3840) |
Every file is saved as JPEG at 94% quality (95% for 4K). A PNG with a transparent background comes out on white.
Does converting to HD make a photo sharper?
No. The converter adds pixels by smoothing between the ones already there, so the photo is bigger but holds the same detail. It helps when a site or printer asks for a minimum size, or when a set of photos needs to match. It cannot fix a shaky or out-of-focus shot.
For one photo where you want sharpening as well as size, use the HD photo converter. To double or quadruple a single image, use the image upscaler; to fix dull light or a colour cast first, the product photo editor. If you need a bigger file in KB rather than in pixels, that is increase image size.
How many photos can you convert at once?
You can select as many as you like. Without an account the tool processes 5 photos a day on one device; if you choose more, it does those 5 and keeps the rest waiting. After that it asks you to sign in to continue (tool code, read 22 Oct 2026).
The photos are read and converted in your browser, two at a time, and only the finished ZIP is saved to your device.
