One shape, a lot of screens
16:9 at 1920 × 1080 is the most common screen shape around. Converting your photos to exactly that size makes them slot in without black bars or awkward zooming:
- Desktop wallpapers on laptops and monitors
- Presentation slides, where a full-bleed photo looks far better than a floating one
- Video thumbnails and title cards in editing apps
- TV slideshows from a USB stick or media player
Fill vs fit for a widescreen frame
Your iPhone photo is 4:3, a bit squarer than 16:9. There are two ways to deal with the mismatch:
| Fill (this page) | Fit | |
|---|---|---|
| Result size | Exactly 1920 × 1080 | Within 1920 × 1080 |
| Black bars | Never | Yes, at the sides or edges |
| Anything trimmed? | Edges that overflow | Nothing |
| Best for | Landscape photos | Portrait photos |
For landscape shots, fill trims a modest strip from the top and bottom and nobody notices. For portraits it keeps only a wide band from the middle. In that case, either crop manually or use Resize HEIC in fit mode.
Making a TV slideshow from your iPhone
Family photo night is the classic use case. A quick routine:
- Sort out sideways photos first with Rotate HEIC. Some TVs ignore the orientation tag.
- Pick your landscape shots and drop them here.
- Download the ZIP, unzip it onto a USB stick, and plug it into the TV.
JPG is the safest output, as it’s the format TVs and media players most reliably support. 1920 × 1080 matches a Full HD panel exactly, and a 4K TV will scale it up cleanly.
Better slides in less time
Presentation apps happily accept a 4 MB phone photo, then make the file huge. Resizing to 1920 × 1080 first keeps your deck light enough to email, and the photo already fills a widescreen slide edge to edge. Want to frame the subject yourself? Crop HEIC has a 16:9 preset.
Fast and local
The resizing runs in your browser, spread across your CPU cores, so a few hundred holiday photos finish quickly. No upload is involved, which also means no waiting on a slow connection.
