Drop multiple images to combine them into one PDF, Word document, or PowerPoint presentation — or convert each image separately.
Drop an image, set your target width and height, and convert. The aspect ratio lock keeps proportions correct so the image never stretches.

Use cases
Social media
Resize to exact platform specs — 1200×630 for Open Graph, 400×400 for profile photos.
Email signatures
Scale a logo to 200px wide so it fits without breaking the layout.
Web optimization
Reduce oversized photos before uploading to a CMS or page builder.
Print prep
Output at a specific pixel count for a given DPI and print size.
Downscaling is safe, upscaling is not
Making an image smaller discards pixels, and a good resampling filter does it cleanly — the result looks sharp because all the detail it needs is already there. Resizing happens with Lanczos resampling, which is a good general choice for photographs and graphics alike.
Making an image larger is a different problem. There is no extra detail to recover, so enlarging invents pixels by interpolating between the ones you have. The result is softer than the original at the new size, and no setting changes that. If you need a larger image, go back to the source at full resolution.
Keep the aspect ratio unless you mean not to
Setting only a width, or only a height, scales the other dimension to match and keeps the image's proportions. Setting both without keeping the ratio stretches the picture, which is almost always a mistake and is immediately obvious on faces and logos.
If you need a specific shape rather than a specific size, crop to the aspect ratio first and then resize. Cropping removes content you choose; stretching distorts everything.
- Resize down from the largest original you have, not from a copy you already shrank.
- For web images, resize to the size they will actually be displayed — serving a 4000px image into a 800px slot wastes most of the download.
- Resize before compressing. Compressing first and resizing after means the compression artifacts get scaled too.

Frequently asked questions
Can I set just the width or just the height?+
Yes. Fill in only one dimension and enable aspect ratio lock — the other dimension is calculated automatically.
Will the image be stretched?+
Not if aspect ratio lock is on. With it enabled, the image is scaled proportionally.
What formats are supported?+
JPG, PNG, WebP, HEIC, GIF, TIFF, BMP, and most common image formats.
