Resize Image to 2480×3508 (A4 at 300 DPI)

Resize Image to 2480×3508 (A4 @ 300 DPI Print)

2480×3508 pixels is a full A4 sheet at 300 DPI — the pixel count a printer needs to render an A4 poster, flyer or document at true print quality. Print shops and home printers work in dots per inch, not pixels, so a photo that looks huge on screen can still print blurry if it doesn't carry enough pixels for the page; 2480×3508 is exactly the A4 print budget at 300 DPI (portrait). This tool crops your artwork to that print canvas on your device, so a document you're about to send to a printer never passes through a cloud service.

Good to know

Outputs exactly 2480 × 3508 pixels — a portrait A4 page (210 × 297 mm) at 300 DPI.

300 DPI is the standard for sharp printing, so this size fills an A4 sheet without pixelation.

"Cover" fit fills the full A4 ratio and trims overflow, so there are no white margins from the resize itself.

For a landscape A4, use the sibling 3508×2480 preset instead (swap width and height).

Leave a printer-safe margin in your design — many printers can't ink the outermost few millimetres of the page.

Frequently Asked Questions

Why is A4 at 300 DPI 2480×3508 pixels? ▼

A4 is 210×297 mm, which is 8.27×11.69 inches. At 300 dots per inch, 8.27 in × 300 ≈ 2480 pixels wide and 11.69 in × 300 ≈ 3508 pixels tall. That pixel count is what a printer needs to render a full A4 page at 300 DPI print quality.

Do I need 300 DPI, or is less fine? ▼

300 DPI is the standard for crisp printed text and photos. You can print at 150–200 DPI for a rougher draft or a poster viewed from a distance, but for a document, flyer or photo held in hand, 300 DPI — and therefore 2480×3508 for A4 — is the reliable choice.

The image is A4 shape but my print has white borders — why? ▼

Most printers have a non-printable margin, so they can't ink right to the paper edge unless you use borderless printing. That's a printer setting, not a resize issue. Keep important content a few millimetres inside the edge so nothing critical falls in the unprintable margin.

Is my document uploaded to resize it? ▼

No. The resize runs on a canvas in your browser, so your print file never leaves your device.
