Resize images for every social media platform
Pick a platform and asset type — profile picture, story, thumbnail, banner — and get an image at the current recommended dimensions, with safe-zone guides where they matter. Everything runs in your browser; nothing is uploaded.
Preset dimensions last verified July 2026 — platforms change specs; we re-check monthly.

How it works
- 1
Choose a platform and asset
Instagram post, YouTube thumbnail, LinkedIn banner, Discord avatar and more — each preset carries the platform's current recommended dimensions.
- 2
Add your image
Drop a file or paste from your clipboard. The preview shows exactly how it fits the target size, including safe-zone overlays for banners.
- 3
Pick crop or fit
Crop-to-fill trims the edges so the frame is completely covered; fit-with-padding keeps the whole image and fills the rest with a color you choose.
- 4
Download one size — or all of them
Save the single result, or export several platform sizes from the same source image as one ZIP.
Common uses
- Sizing an Instagram post or story before publishing
- Making a YouTube thumbnail that stays sharp at every size
- Fitting a LinkedIn or X banner without awkward cropping
- Creating matching profile pictures across every network
- Preparing Twitch panels and Discord server assets
- Exporting one campaign visual in every platform's size at once
Why the presets stay trustworthy
Most "social media size" cheat sheets go stale within months because platforms quietly change their recommendations. PNGful keeps its presets in a maintained registry: every preset records when its dimensions were last verified and where to re-check them, and we review the whole set monthly. The current set was last verified in July 2026.
Banners are where sizing goes wrong most often, because the same image displays differently on different devices — a TV, a desktop browser and a phone each show a different slice of a YouTube channel banner, for example. For those presets, PNGful overlays the platform's safe zone so you can see exactly which region survives on every device and keep text and logos inside it.
When your image's aspect ratio doesn't match the target, you decide how to resolve it. Crop-to-fill scales the image until it covers the full frame and trims the overflow — best for photos. Fit-with-padding shrinks the image to fit entirely inside the frame and fills the remainder with a background color — best for logos and graphics that must not be cut.
Good to know
- Preset dimensions are platform recommendations, not guarantees — platforms can change specs at any time, which is why each preset shows when it was last verified.
- Platforms re-compress everything you upload, so the file you see here won't be byte-identical to what viewers see.
- Safe-zone overlays reflect the platform's published guidance; some clients or future redesigns may crop differently.
- Animated inputs are processed as a single still frame.

Frequently asked questions
What size should an Instagram post be?
As of our July 2026 verification, Instagram recommends 1080 px wide: 1080 × 1080 for square posts, 1080 × 1350 for portrait (4:5), and 1080 × 566 for landscape. Portrait posts occupy the most feed space. Pick the Instagram preset here and the tool applies the current numbers for you.
Why does my banner get cropped differently on TV and mobile?
Banner-style assets — YouTube channel art especially — are one large image from which each device shows a different region. A TV displays nearly all of it, while a phone shows only a narrow central strip. That's why the banner presets include a safe-zone overlay: keep anything important inside it and the banner works everywhere.
Will the platform compress my image after I upload it?
Generally yes. Almost every platform re-encodes uploads to save bandwidth, so some quality loss on their end is unavoidable. The best defense is uploading at the recommended dimensions in a high-quality file, so the platform's compression starts from the best possible source.
Can I export several sizes at once?
Yes. From a single source image you can generate multiple platform sizes in one pass — say, a square post, a story and a banner — and download them together as one ZIP, each file named for its platform and asset type.
Should I choose crop-to-fill or fit-with-padding?
Use crop-to-fill for photos: it covers the whole frame and trimming the edges is usually invisible. Use fit-with-padding for logos, text and graphics where losing edges would be a problem — the entire image is preserved and the leftover space is filled with a color you pick.
