JPG fills transparency with white. HEIC exports the first decoded image. Metadata, color profiles, and animation may change. Always keep your originals.
Fit images within the dimensions you need
Enter a maximum width, height, or both. With Keep Aspect Ratio enabled, Picvexa fits the image inside those bounds without stretching. It never enlarges a smaller original. Disabling the ratio setting limits each dimension independently and may distort the image.
When to Use This Tool
- Fit a landscape photo within a 1280 × 720 boundary.
- Reduce square images from 1000 × 1000 to 500 × 500.
- Limit only width or height while preserving proportions.

Frequently Asked Questions
Helpful answers before you convert.
What happens if I enter only width?
With aspect ratio enabled, height is calculated proportionally. With the ratio disabled, width is limited independently and the original height is retained.
Why is my output smaller than the box I entered?
The fields are maximum bounds, not a crop size. Aspect ratio fitting may leave one dimension below its limit, and the tool never enlarges a smaller original.
Can I make a square crop from a wide photo?
No. There is no crop operation. Turning the ratio off may stretch the image; it does not select or remove part of the photo.
What are the size limits?
Each dimension input is capped at 12,000 pixels. Source images must fit the 24-megapixel limit, with 25 MB per file and 100 MB per queue. A memory-constrained device may still need smaller images.
