Every size above is exported by the resizer at the top of this page. The table is generated from the tool’s own preset definitions, so it cannot describe a size the export does not produce.
Designing for Pinterest
A mosaic feed rewards height
Most social feeds are a single column of fixed-width slots, so a taller image occupies more of one screen and then scrolls away. Pinterest lays pins out in columns of varying height, and a taller pin occupies more of the visible mosaic for longer as the user scrolls.
That is a structural difference, not a stylistic preference, and it is why 2:3 is the standard here while 4:5 is the standard on Instagram. The extra height is not decoration; it is visibility.
It also has a limit. Extremely tall pins are truncated in the feed with a tap-to-expand, which costs you the end of the composition. 2:3 is the shape that gets the benefit without the truncation.
Pins are read, not just seen
Pinterest is closer to a search engine than to a feed: people arrive with an intention and scan for something that matches it. Text on the image does real work here, where on most platforms it is a liability.
That means a pin can carry a title, and should. It also means the title has to survive being rendered at a few hundred pixels wide in the mosaic, so it wants to be short and set large — the same discipline as a YouTube thumbnail, for the same reason.
Square pins, and when to use them
The square pin exists mostly for content that is genuinely square — a product shot, a single object, a photograph that would be ruined by a 2:3 crop.
It gives up the mosaic advantage, so use it when the image demands it rather than as a default. If the choice is a good square image or a badly cropped 2:3 one, take the square: a broken composition loses more than the extra height gains.
One more habit worth forming here: pins have a much longer useful life than posts on any other platform, often resurfacing months or years after publication. That makes it worth keeping dates, prices and anything else time-bound off the image itself — the pin will still be circulating long after the offer has expired.
1080 pixels wide, with the height set by the shape you want: 1350 for the portrait format that occupies the most feed space, 1080 for a square, and 566 for landscape. Stories and Reels are 1080 × 1920. The exact numbers for every format this tool exports are in the reference table above, generated from the presets themselves rather than typed from memory.
What size is a YouTube thumbnail?
1280 × 720, a 16:9 frame. That is YouTube's recommended size and the one this tool exports. Design for it to be legible at roughly 210 pixels wide, which is how big it will actually be in a sidebar — a thumbnail that only works at full size is a thumbnail that does not work.
How do I resize one image for every platform at once?
Select every destination you need, then export. The tool crops your image separately for each target ratio, resizes each crop to that platform's pixel dimensions, and packages the whole set into one ZIP with descriptive filenames. One upload of effort, one download, every size correct.
Will my subject get cut off?
Not usually. Rather than cropping from the centre, the tool looks for a face in the image and falls back to a saliency estimate — the region with the most visual detail — then places the crop window around that point. You can nudge the framing afterwards if it chose differently from you, which matters most for the extreme ratios like a 1500 × 500 header.
Is this free?
Completely. Every step runs in your browser using WebAssembly codecs, so there is no server cost for us to pass on. No sign-up, no watermark, no cap on how many images or how many sizes. The Pro plan adds AI tools and AVIF output; social resizing stays free.
Are my photos uploaded?
No. Decoding, face detection, cropping, resizing and ZIP creation all happen on your device. Nothing is transmitted, nothing is stored on our side and nothing needs deleting afterwards — which is what makes this usable for client work and unreleased campaign material.
Does resizing for social media reduce quality?
Downscaling is the safe direction and this tool uses Lanczos resampling, which preserves detail better than the simpler filters most browsers apply by default. The real risk is starting too small: exporting a 1080-pixel image to a 2560-pixel YouTube banner means enlarging, and enlargement cannot add detail that was never captured. Start from the largest original you have.
What is the safe area, and why do my Stories get covered?
A 1080 × 1920 Story is full-screen, and the platform draws its own interface on top of it: your profile and name across the top, and reply controls, captions and buttons across the bottom. Roughly the top and bottom 250 pixels are contested. Keep text and faces in the middle band and use the outer regions for background, or the app will place a Send button over your headline.
Should I export as JPG, PNG or WebP?
The tool picks a sensible output format from your source, keeping PNG where transparency needs preserving and using a lossy format where it does not. For social specifically the choice matters less than people expect, because every platform re-encodes what you upload anyway. What does matter is uploading at the full recommended dimensions, so the platform's own compression starts from a large, clean image.
Why do platforms keep changing their image sizes?
Because the surfaces change. A new full-screen video format, a redesigned profile page or a different feed layout all move the goalposts, and the recommended dimensions follow. That is exactly why the size table on this page is generated from the presets the tool actually exports rather than written into an article: when a preset is updated, the documentation updates with it instead of quietly becoming wrong.
