Resizing to 5 × 7 inch photo print
The ratio nobody shoots
5 × 7 is a 5:7 ratio, about 1:1.4. A camera gives you 3:2, about 1:1.5. A phone gives you 4:3, about 1:1.33. Neither matches, and 5:7 sits awkwardly between them, so a 5 × 7 print always requires a decision.
From a 3:2 photograph in portrait orientation, reaching 5:7 means losing roughly 7% of the height. From a 4:3 photograph, it means losing about 5% of the width. Both are small, and both land on an edge, which is where the important thing usually is not — but check.
This is why 5 × 7 flatters portraits and frustrates landscapes. A face in the middle of the frame survives any of these crops; a horizon that reached the edge does not.
Why 1500 × 2100
Five inches at 300 DPI is 1500 pixels and seven inches is 2100. That is the portrait orientation, which is the usual one for this size.
For a landscape 5 × 7 the numbers swap to 2100 × 1500. Labs treat the two as the same product, so supply the image the way round you want it and do not rely on anyone rotating it for you.
A 12-megapixel photograph comfortably exceeds the 3.2 megapixels this needs, so the resize is a downscale and costs nothing in quality.
Framing eats the edges
A 5 × 7 frame's rebate — the lip that holds the print — covers roughly 3 to 5 millimetres on each side. A mount cuts considerably more, often 10 millimetres or more.
That is real: a portrait cropped tightly enough that the top of the head touches the edge will have the top of the head hidden by the frame. Leave a margin you can afford to lose, and if the print is going behind a mount, leave a generous one.
Yes. Resizing JPG, PNG, and WebP images is completely free with no sign-up, no watermark, and no file limit. Resizing runs entirely in your browser, so there is nothing for us to charge for. Pro plans add the AI tools, but everyday resizing stays free forever.
Are my images uploaded to a server?
No. OpusImg resizes images on your own device using WebAssembly and your browser's own canvas. Your files never leave your computer or phone — there is no upload, no cloud processing, and nothing stored on our side. That makes it safe for confidential documents, client work, and personal photos.
How do I resize an image to exact pixel dimensions?
Choose the "By dimensions" mode and type the width and height you need in pixels. Leave the aspect-ratio lock on to keep the image's proportions — change one field and the other follows automatically. Turn the lock off when you need an exact, possibly non-proportional canvas, such as a specific banner size.
What is the lock aspect ratio toggle for?
When the lock is on, the width and height stay proportional: setting the width to 1000px updates the height to match the original shape, so the picture is never squashed or stretched. When the lock is off, you can set width and height independently, which is useful for fitting an exact canvas even if it distorts the image slightly.
Which resampling algorithm should I pick?
Use Lanczos for photographs — it produces the sharpest, most natural result and is the default. Bicubic is a fast, smooth alternative handled by your browser. Choose Nearest neighbour only for pixel art, sprites, or icons where you want hard edges and no blending between pixels when scaling up.
What does the DPI setting do?
DPI (dots per inch) is metadata that tells print software how large to print the image. It does not change the pixel dimensions or how the image looks on screen — 72 DPI is standard for the web, while print shops usually want 150 or 300 DPI. We embed the value you choose into the file (PNG and JPG) so a print workflow reads the right density.
Can I resize for Instagram, YouTube, or other platforms?
Yes. The "By preset" mode includes 18 ready-made sizes — Instagram square, portrait, and story; Facebook and LinkedIn covers; X/Twitter headers; YouTube thumbnails and channel art; Pinterest pins; plus HD, QHD, and 4K. Pick a preset and your image is resized to the exact canvas that platform expects.
Will resizing reduce image quality?
Making an image smaller (downscaling) keeps it looking crisp — Lanczos and bicubic both average pixels cleanly. Making it larger (upscaling) can only invent so much detail, so very large enlargements look soft; for big upscales the AI upscaler in Pro reconstructs detail far better. We encode the result at high quality so the resize itself adds no visible compression artifacts.
Can I resize many images at once?
Yes. Drop a whole folder and apply one target to the batch. In percentage mode every image is scaled by the same percentage, so each keeps its own aspect ratio; in dimensions or preset mode every image is fitted to the same canvas. Results are bundled into a single ZIP for download, all processed on-device.
What formats can I resize?
You can drop in JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, and HEIC. Each file is decoded in your browser, resized, and re-saved — JPG and HEIC come out as JPG, PNG/BMP/TIFF as PNG, and WebP/AVIF/GIF as WebP, so the result always opens everywhere.
