Crop to fill the frame
Use Crop when the final image should fill every edge. The image ratio converter removes parts outside the frame. Drag the frame to keep a face, product, or other subject in view; use Crop zoom to focus on a smaller area.

Crop or pad: choose what happens to your image
The same target ratio can produce two different results. Choose the one that keeps what matters.
Pad to keep the whole image
Use Pad when every part needs to remain visible. The photo fits inside the new shape, with extra space above and below or on either side. Pick a background color, or export PNG with transparent padding. The original photo keeps its proportions.
When to change an image's aspect ratio
Fit your image to where it will appear. These starting points help you choose a shape and decide what to keep.
4:5
Social media posts
Turn a landscape photo into a portrait post while keeping a face, outfit, or other subject in view. A 4:5 output can use 1080 × 1350 pixels.
Crop
Move the frame around the subject. Choose Pad instead when the whole artwork or its text needs to stay visible.
9:16
Stories and phone wallpapers
Prepare a tall image for a story layout or phone wallpaper. A 9:16 frame gives you a vertical canvas, such as 720 × 1280 pixels.
Crop
Fill the tall frame with your subject and leave space near the edges for any controls or text in the final layout.
16:9
Video thumbnails and slides
Fit a photo or graphic into a widescreen video thumbnail or presentation slide. Start with a 16:9 canvas, such as 1280 × 720 pixels.
Crop or Pad
Crop a photo to fill the frame. Pad a chart, screenshot, or graphic when cropping would cut off useful information.
1:1
Product listings and catalogs
Give product photos a consistent square shape for a shop grid or catalog. Keep the whole item visible, including packaging, labels, and outer edges.
Pad
Use the same padding color and output dimensions across your images for a consistent product grid.
5:2
Website banners and headers
Adapt a photo to a wide website banner or header without stretching it. A 5:2 layout can use 1000 × 400 or 1500 × 600 pixels.
Crop
Keep the important subject inside the wide frame. Use a custom ratio when your website's banner slot has a different shape.
4:5 / 5:2
Application photos and signatures
Match a form that asks for a 4:5 portrait photo or a 5:2 signature image. Set the pixel dimensions and format specified by that form.
Follow the form's rules
Crop a photo when a filled frame is required. Pad a signature only if borders are allowed, keeping every stroke visible.
How to change an image's aspect ratio online
Choose your image
Open a PNG, JPG, or WebP, or try the sample already in the editor. Your file is processed on your device.
Select the new shape
Choose a ratio preset or enter a custom width-to-height ratio, such as 5 and 2.
Compare crop and pad
Crop for a filled frame, or pad to keep the whole photo. Check the live preview before exporting.
Set the size, then copy or download
Choose your output dimensions and format. Copy the result as PNG, or download PNG, JPG, or WebP. Width and height remain linked to the selected ratio.
Common image aspect ratios and pixel sizes
A ratio defines a shape, not one fixed resolution. Select a ratio below to try it in the editor.
| Ratio | Example size | Typical uses |
|---|---|---|
| 1000 × 1000 px | Avatars, logos, product tiles | |
| 1080 × 1350 px | Portrait posts and vertical layouts | |
| 1000 × 400 px | Wide banners and signature layouts | |
| 1280 × 720 px | Video thumbnails and slides | |
| 720 × 1280 px | Story layouts and phone wallpapers | |
| 1200 × 900 px | Photos and presentation graphics | |
| 900 × 1200 px | Portrait cards and document images | |
| 1200 × 800 px | Photography and print layouts | |
| 800 × 1200 px | Portrait photography and posters |
For example, 1000 × 400, 1500 × 600, and 2000 × 800 all have a 5:2 landscape ratio. A 4:5 portrait image might be 800 × 1000 or 1080 × 1350. Increasing the resolution does not change the shape, and enlarging a small source cannot recover missing detail.
Social platforms and application forms may accept several shapes or apply their own crop. Check the requirements for your specific placement, rather than assuming one ratio works for every upload.
Fix an “image must have 5:2” or “4:5” aspect ratio error
Match the required shape, then check the remaining upload rules.
If an upload says “image must have 5:2 (landscape),” choose 5:2 in the editor. For “image must have 4:5 (portrait) aspect ratio,” choose 4:5. Those are width-to-height ratios: reversing the numbers changes the orientation.
Use Crop when the form requires an image that fills the frame. If all of a signature, document, or product must remain visible, Pad can preserve it, but first check whether that form allows borders or padding. Select the required pixel size and format before downloading.
A correct ratio alone does not guarantee approval. Forms can also reject the file because of its size in KB, resolution, background, or visible content. If the ratio is correct but the file is too large, use Reduce Image Size in KB and check that the final dimensions still meet the upload rules.
Image aspect ratio changer FAQ
What is an image aspect ratio?
An aspect ratio describes an image's width compared with its height. A 5:2 image is 2.5 times as wide as it is tall; a 4:5 image is taller than it is wide. The ratio describes the shape, not the file size or a single required resolution.
How do I change the aspect ratio of an image without cropping?
Choose your target ratio and select Pad. The tool fits the whole image inside the new shape and fills the remaining space with your chosen color. Choose PNG and enable transparent padding if you want the extra space to stay transparent.
Will changing the image ratio distort my photo?
Both Crop and Pad keep the photo's proportions. Crop removes outer areas; Pad adds space around the whole image. Neither mode stretches the picture. Exporting a small photo at a much larger pixel size can still make it look softer.
How do I convert an image to a 5:2 landscape ratio?
Select 5:2, choose Crop or Pad, then copy the result or download it. The default output is 1000 × 400 pixels. You can also use 1500 × 600 or 2000 × 800. For a signature, check that the full signature remains visible and that the receiving form allows padding.
How do I convert a photo to a 4:5 portrait ratio?
Select 4:5 to start with a 1080 × 1350 pixel output. Move the crop frame to keep the important subject, or select Pad to preserve the whole photo. Change either output dimension to choose another size with the same 4:5 ratio.
Does fixing the aspect ratio guarantee that an upload will be accepted?
No. An upload form may also check pixel dimensions, file size, format, background, and the visible content. Fix the ratio, then check those other requirements against the form's instructions. This tool does not certify a photo or signature for a particular application.
Why does the other output dimension change automatically?
Width and height stay locked to the selected ratio. Whole-pixel output dimensions are adjusted to the nearest matching pair, so a 5:2 export might use 1000 × 400 rather than an almost-matching size. Export is limited to 12,000 pixels per side and 40 megapixels.
Is this photo ratio changer free, and does it upload my image?
The tool is free to use without an account or watermark. Your chosen image is opened, previewed, and exported in your browser; it is not uploaded to an image-processing server. You can copy the result as PNG or download PNG, JPG, or WebP.
