Social Media Image Resizer
Resize images for Instagram, Facebook, LinkedIn, YouTube, X, Pinterest, TikTok, stories, reels, and Open Graph cards using exact pixel presets — all processed locally in your browser.
What the platform presets cover
Social Media Image Resizer reshapes an image to a set of commonly used canvas sizes for Instagram, Facebook, LinkedIn, YouTube, X, Pinterest, TikTok, and Open Graph cards. These presets remove the arithmetic from preparing several versions, but they are starting points rather than permanent platform rules. A network may crop or pad an image differently by placement, device, or later product update, so preview the upload before publishing.
The resizer supports two layout modes. Fit mode preserves the entire image and adds padding in your chosen background color when the aspect ratio does not match the preset. Fill mode crops the image to cover the full frame edge to edge, which is ideal for thumbnails and banner graphics where full coverage looks more polished. You can also choose the output format — JPG, PNG, or WebP — depending on what the platform accepts and whether you need transparency.
When presets beat manual cropping
Use a preset when you want a repeatable canvas for a Facebook link preview, Instagram carousel image, YouTube thumbnail, or LinkedIn post. Fit mode is useful when every part of the source must remain visible; Fill mode is useful when edge-to-edge coverage matters more than preserving the outer edges. Neither mode can predict a platform's final responsive crop, so keep faces, logos, and small text away from the boundary and inspect the upload preview.
The same workflow helps when repurposing one image across several placements. Run the source through the sizes you need, inspect each crop separately, and keep the original so you can revise a version without enlarging an already resized copy.
Export format for social uploads
JPG is a practical default for photographic posts because it is widely accepted and usually smaller than a comparable PNG. PNG can be the better working copy for flat graphics, sharp text, or transparency, although a destination may flatten transparency or re-encode the upload. WebP can reduce transfer size, but acceptance varies among platforms and scheduling tools. Check the current upload form, compare the downloaded result, and keep the source file rather than assuming one export format is best for every placement.
Social Media Image Size Reference
Use this table as a set of working sizes, in pixels (width by height). Platform specifications and presentation rules change; verify the current destination guidance and its upload preview before publishing a campaign asset.
| Platform | Use Case | Dimensions | Aspect Ratio | Notes |
|---|---|---|---|---|
| Square post | 1080 x 1080 | 1:1 | Common square starting point; placement may change the crop | |
| Portrait post | 1080 x 1350 | 4:5 | Common 4:5 feed canvas; keep key content away from edges | |
| Instagram / TikTok | Story / Reel | 1080 x 1920 | 9:16 | Vertical starting point; leave room for interface overlays |
| Link preview | 1200 x 630 | 1.91:1 | Common link-card canvas; the destination may crop it | |
| Feed post | 1080 x 1080 | 1:1 | Square feed starting point | |
| X (Twitter) | Timeline image | 1600 x 900 | 16:9 | Landscape starting point; feed presentation can vary |
| Article / post | 1200 x 627 | 1.91:1 | LinkedIn documents 1.91:1 for Page link-post images | |
| YouTube | Thumbnail | 1280 x 720 | 16:9 | 16:9 baseline preset; check YouTube's current larger recommendation |
| Standard pin | 1000 x 1500 | 2:3 | Common 2:3 image Pin canvas | |
| TikTok | Cover / video | 1080 x 1920 | 9:16 | Vertical working size; preview interface-safe areas |
| Open Graph | Link card | 1200 x 630 | 1.91:1 | Common link-preview canvas; rendering differs by service |
How To Resize For Each Platform
- Upload one or more images from your device using the file picker or drag and drop.
- Select the social media preset that matches your target platform and post type.
- Choose fit mode to preserve the whole image with padding, or fill mode to crop for full-frame coverage.
- Click Convert, then download the resized image ready for upload to your social platform.
Frequent Social Resizing Mistakes
Uploading a tiny source image and expecting a sharp result at 1200x630 or larger. Always start with a source image at least as large as the target preset.
Using fill mode for images with important content near the edges. Fill crops to fit the frame, so faces or text near borders may be cut off.
Forgetting to change the preset when switching platforms. An Instagram square uploaded to YouTube will display with heavy letterboxing.
Choosing a format by habit instead of the destination. JPG is often compact for photos; PNG may better suit sharp text or transparency; WebP acceptance varies. Check the upload form and inspect its preview.
Frequently Asked Questions
Which platforms and post types do the presets cover?
The presets target the dimensions common slots expect, including Instagram Square and Portrait, Story or Reel, Facebook Post, LinkedIn Post, an X post size, YouTube Thumbnail, and an Open Graph image for link previews. Picking the one that matches your platform and post type sets the right pixel size, so you are not guessing dimensions for each network separately.
What is the difference between Fit whole image and Fill and crop?
Fit whole image keeps your entire picture visible inside the preset frame, adding background where the shapes differ so nothing is cut off. Fill and crop instead scales the image to cover the whole frame and trims the overflow, filling the slot edge to edge but cropping the parts that do not fit. Choose Fit to keep everything, or Fill for a full-bleed look.
When does the background color come into play?
It fills the empty space that Fit whole image leaves when your picture's shape does not match the preset, for example a landscape photo placed in a tall story frame. Set it to match your design, often white or a brand color, so the padding looks intentional. With Fill and crop there is no empty space, so the background color does not show.
