Resize Images
Smaller dimensions also mean a smaller file. If you need a specific file size, use Compress Image.
Exactly the size you need
Image size is measured in pixels (width × height). Phone photos are often 4032×3024, far bigger than needed for the web or email. This tool resizes many photos at once with the same rule.
Four ways to fit
- Keep aspect ratio (fit inside) — scales the photo to fit within the width and height. Fill in just one and the other is calculated.
- Crop to fill — fills the exact size and trims the overflow from the center. Great for square posts and thumbnails.
- Pad to fill — keeps the whole photo and fills the leftover space with a color. Common for product photos.
- Stretch — forces the exact size, ignoring the ratio; the photo may look squashed.
By percent scales to 50%, 25% and so on. If you enlarge beyond the original, you'll get a blur warning.
Quality
Big reductions are done in several halving steps so text and lines don't turn jagged. The new size is added to each file name. Photos are never uploaded.
Common sizes
Instagram feed: 1080×1080 (square) or 1080×1350 (portrait). YouTube thumbnail: 1280×720. Web posts: 1200–1920 px wide is plenty. Picking a preset sets the width, height and fit for you.
Frequently asked questions
Does this change the DPI?
For screens, pixel count is what matters. Print size is pixels ÷ dpi — a 4-inch print at 300 dpi needs 1200 px.
What happens to transparent PNGs?
Saving as PNG or WEBP keeps transparency; JPG fills it with white.
My photo's orientation changed.
The photo's rotation tag is applied, so it's saved the way it looks on screen. Rotate it in a photo editor first if you need a different orientation.
