Resize a Photo to Poster SizeFree

To resize a photo to poster size, drop a PNG, JPG or PDF, pick a size (A0–A5, 8×10, 11×14, 12×16, 16×20, 18×24 or 24×36 in, 50×70 cm, or your own) and choose Crop, Stretch or 50/50 to fit the new shape, then download a print-ready JPG. Each file is rated in real DPI at that size: 150 DPI or more is good for print, 100–149 DPI suits smaller prints. This tool doesn’t add pixels: to enlarge a small image, make it print-ready first, which upscales it with AI to the exact size at 300 DPI.

Free, no sign-up, no watermark. Runs in your browser — your files are never uploaded.

How to resize a photo to poster size

Drop your file
A PNG, JPG or PDF, or several at once.
Pick a poster size and how it fits
A-series, inch or cm sizes, or type your own like 50x70cm. Crop, Stretch or 50/50 shapes the image to the new ratio, and each file gets a DPI rating.
Download
Save a print-ready JPG, or every file at once as a ZIP.

Standard sizes: A0–A5, 8×10, 11×14, 12×16, 16×20, 18×24, 24×36 in, 50×70 cm and more
Portrait or landscape: one click turns every size on its side for wide posters
Custom sizes: type e.g. 50x70cm, 13x19in, or a bare ratio like 5x7
Crop trims to fit — drag, use arrow keys, or double-click to re-centre
Stretch fills the size exactly; 50/50 splits the difference
Vector PDFs render razor-sharp at any size; PNG/JPG export at their own resolution
Download one file as JPG, or every file at once as a ZIP

Made for Etsy and Shopify poster sellers

Print-on-demand partners and local print shops all want a specific pixel size at a specific DPI, and a design file that's the wrong ratio gets cropped in ways you didn't choose. This tool is built for the poster and wall-art workflow: drop your master file once, generate every size your listing needs, and see a real quality warning before a print comes out blurry — not after a customer complains.

Starting from a small AI design? Make it print-ready first: the AI upscales it to the exact poster size at 300 DPI, with bleed if your printer asks for it.

FAQ

Is this poster resizer really free?

Yes — resizing PDFs, PNGs and JPGs for print is completely free, with no sign-up, no watermark and no limit on how many files you convert. Scaylr makes money from its mockup generator, not this tool.

Does my file get uploaded anywhere?

No. Everything runs in your browser using Canvas and PDF.js. Your PDF, PNG or JPG is never sent to a server — it stays on your device the whole time.

What's the difference between Crop, Stretch and 50/50?

Crop trims the edges to fit the new size with no distortion — drag to choose what stays. Stretch distorts the whole image to fill the size exactly. 50/50 is a middle ground: it crops away half of the excess, then gently stretches the rest, so it's less cropping than Crop and less distortion than Stretch.

How do I know if my print will look sharp?

Each file gets a quality badge based on its real source resolution at the size you picked: green means good for print, amber means fine for smaller prints, and red warns you before you download that it may look blurry. A vector PDF is always sharp, whatever size you choose.
