Image Canvas Resizer
Choose a canvas size, in pixels or a print size like A4 or Letter, then drag and resize your image on it, the way a design app does. Add as many pages as you need and save them as images or one PDF.
How to use this tool
In the Size tab, type a Width and Height in px, in, cm or mm, or pick one of the Popular sizes, such as Product square, A4 portrait or US Letter. For a print size, choose a Print quality: High is what print shops ask for.
Drop an image on the page and use Add image to page for more layers. Fit shows the whole image, Fill covers the page and Center puts it in the middle; drag it to move it, resize it with any of its eight handles, or press Remove background to cut out the subject. In the Image tab, drag the layer handles to change their order. Undo and Redo also restore deleted and reordered layers.
Use Fit view, Fit width or View zoom to enlarge the workspace without changing the download size. Add page starts a blank page and Duplicate copies one. In the Download tab, choose a file name, format, size and quality, then press Download.

The right size, with your image exactly where you want it.
A shop wants a 2000 × 2000 square, a printer wants A4 at 300 DPI, and a listing wants white space around the product. Set the canvas once, then place each image on it.
- Any size, in any unit
- Type pixels, inches, centimetres or millimetres, or pick a ready-made size. Print sizes become pixels at the DPI you choose, and the DPI is saved in the file so it prints at the right size.
- Drag, resize and snap
- Move an image, resize with eight handles or type an exact percentage. Select, delete or drag layers to reorder them, with undo and redo for edits. View zoom and fullscreen give you more room to work without changing the export size.
- As many pages as you need
- Add, duplicate, reorder and delete pages, or drop several images at once for one page each. Save every page in one PDF, or as numbered images in a zip.
Frequently asked questions
How do I put an image on a white square background?
Choose Product square (1200 × 1200 px) or type your own size, keep the background on white, and drop the image on the page. Fit makes it as large as it can be with all of it showing; lower the Size slider to leave a margin around it, then download a PNG or JPG.
How many pixels is A4 at 300 DPI?
2480 × 3508 pixels for A4 portrait (21 × 29.7 cm), and 2550 × 3300 pixels for US Letter (8.5 × 11 in). The tool shows the pixel size for whatever print size and DPI you choose, under the size fields.
What DPI should I use?
300 DPI for anything printed up close, such as documents, photos and flyers. 150 DPI is fine for posters seen from a distance. For screens and websites, only the pixel size matters, so 72 or 96 DPI is plenty.
Will my image be stretched?
No. All eight resize handles scale the image evenly. A canvas of a different shape leaves space around the image or, with Fill, crops its edges. The tool warns you when the image is enlarged so much that it may look soft.
Can I make a PDF with several pages?
Yes. Add pages with Add page or Duplicate, or drop several images to get one page each, then choose PDF. Every page is saved at the exact printed size, ready to print or send. As images, the pages download as a zip, numbered in order.
Can I put more than one image on a page?
Yes. Press Add image to page, or drop images on a page that already has one. Each becomes a layer. Drag the layer handles in the Image tab to change the order; the top row is in front. You can also focus a handle and use the up/down arrow keys, Home or End. Undo and redo restore the order. Match another image gives a layer the same width, height or centre as another image.
Does View zoom change the downloaded image size?
No. View zoom only changes how large the page looks while you edit it. Fit view shows the whole page, Fit width uses the available width, and fullscreen gives you more workspace. Image size percentage changes an image on the page; canvas dimensions and Download size control the exported file.
Can it remove the background from a product photo?
Yes. Select the image and press Remove background. Flat graphics on an even backdrop are cleaned straight away; photos use the same AI engine as the Background Remover. Model files are downloaded and cached on first use. Your picture stays on your device and keeps its size and place in the layout. You can cancel while processing, and Restore background puts the original back.
Can I use iPhone HEIC photos?
Yes. A HEIC or HEIF photo is converted in your browser as it is added, the same way the HEIC to JPG converter does it, and then placed like any other image.
Can I change the file name?
Yes. Type it in File name before you download. The extension follows the format you choose, so the name never says PNG on a JPG.
