Image Tools

Social Media Resize

Resizes one image to the exact pixel size of a chosen social platform format, such as 1080×1080 for an Instagram post. A live preview shows what is kept, and a slider lets you choose which part of the picture stays.

About this tool

Updated October 6, 2026

Ten presets, each with its own page

You pick a platform format and the tool outputs exactly that width and height, scaling to cover and cropping the overflow.

The presets are Instagram Post 1080×1080 and Instagram Story 1080×1920; YouTube Thumbnail 1280×720 and YouTube Banner 2560×1440; Facebook Post 1200×630 and Facebook Cover 851×315; LinkedIn Banner 1584×396; X/Twitter Header 1500×500; Pinterest Pin 1000×1500; TikTok Cover 1080×1920. What each platform actually publishes is on its own page, with a link to the platform’s help article: Instagram Post, YouTube Thumbnail, YouTube Banner, Facebook link preview, Facebook Page cover, LinkedIn Banner, X Header, Pinterest Pin and TikTok Cover. There is no custom size box here and no padding or blur-background option.

What happens to a photo that is the wrong shape

A landscape photo turned into a square or a tall story loses its sides; nothing is stretched or letterboxed. A slider decides which part survives.

The image is enlarged or reduced until both dimensions are at least as big as the target, and the excess is trimmed. Very wide targets such as a 1584×396 LinkedIn banner keep only a thin band of a normal photo, so the slider matters most there. The preview uses the same placement rule as the exported file. One image is processed per run.

Where a preset and the platform’s own figures differ

Some presets are safe, familiar sizes rather than the exact figure a platform now recommends, and the individual pages say which.

YouTube’s current help page recommends 3840×2160 for thumbnails; 1280×720 is accepted but smaller. Facebook’s 1200×630 is the size for the image shown with a shared link, not for photos posted directly. Instagram accepts shapes from 1.91:1 to 3:4 at up to 1080 pixels wide, so a square is a choice rather than a rule. Facebook’s Page cover is documented at 851×315, which is why that preset changed from 820×312.

Limits to expect

Enlarging a small image will look soft, and platforms may still recompress the file you upload.

Enlarging a small source cannot add detail, and the page tells you by how much it is enlarged. Text near the edges of the original can be cut off by the crop. If the subject needs to keep its whole frame, Canvas Resize adds space around the picture instead, and Image Crop lets you cut an exact region first.

Resizing Images for Social Media and Print, Without the Guesswork
Pixels, aspect ratios and print sizes are three separate ideas. Here is how to calculate the size you need and resize or crop to it cleanly.

FAQ

Does it stretch my picture to fit?

No. It scales the image up or down until it fills the whole target rectangle and trims the overflow. Proportions stay correct, but part of the picture is cut off whenever the source and target shapes differ.

Can I choose where to crop?

Yes. When the picture is a different shape from the frame, a slider moves the crop along the direction that overflows, left to right or top to bottom, and the preview shows the result. When the shapes already match, nothing is cropped.

Are the sizes what each platform wants today?

For nine of the ten, the dedicated page quotes the platform’s own help article and the date it was read. Instagram Story has no dedicated page yet, so its 1080×1920 is the common 9:16 size rather than a figure from a platform page. Platforms change their rules, so check the platform if exact placement matters.

What file type do I get back?

Under File type you can keep the original type, or choose JPEG or PNG. A source in a type that platforms often reject, such as WebP or HEIC, is written as JPEG unless you choose PNG.

Is my image uploaded?

No. Resizing happens in your browser, and the file is not sent to a server for this job.
