About this tool
Posting the same image across Instagram, X, LinkedIn, and YouTube usually means hand-resizing in Figma or Photoshop five times. WRRK's social media resizer does it in one step: drop one source, pick your platforms, get a ZIP with all 11 sizes ready to upload. Each output uses cover-cropping — the image fills the target dimensions while preserving its aspect ratio and centering the subject.
The whole pipeline runs in your browser using the Canvas API for resizing and JSZip for the ZIP packaging. Your image never gets uploaded — important if you're working on unannounced product launches, brand materials, or anything else you'd rather not send to a third-party server. JPG output keeps the ZIP under a megabyte for typical social posts; PNG output is lossless for screenshots, logos, and anything with sharp edges.
How to resize for every platform (5 steps)
- Drop your source image. Use the highest-resolution version you have (2560+ px wide is ideal — covers the biggest output).
- Pick the platforms. Tick the platforms and sizes you need — Instagram square, FB cover, X header, LinkedIn banner, YouTube thumbnail, etc.
- Pick output format. JPG (smaller, faster uploads) or PNG (lossless, supports transparency).
- Generate. Click 'Generate' to render every selected size with a cover-crop. Each output is shown with a preview.
- Download ZIP. Download all selected sizes in a single ZIP file. File names include the platform and size for easy sorting.

Frequently asked questions
+−Which platform sizes are included?
11 of the most-used: Instagram (square 1080×1080, story 1080×1920, portrait 1080×1350); Facebook (cover 851×315, profile 180×180); X/Twitter (header 1500×500, profile 400×400); LinkedIn (banner 1584×396, profile 400×400); YouTube (thumbnail 1280×720, banner 2560×1440).
+−How does the resize handle different aspect ratios?
Each output uses cover-crop — your image scales to fill the target dimensions, preserves aspect ratio, and centres the crop. So a portrait photo stays a portrait when fit into a square Instagram post, with edges trimmed.
+−Will my source image be uploaded to a server?
No. Resize, crop, and ZIP packaging all run in your browser using the Canvas API and JSZip. Your image and the generated ZIP never leave your device.
+−What output format does each file use?
JPG by default — smaller files, fast uploads. Switch to PNG for lossless output (good for logos, screenshots, and graphics with sharp edges or transparency).
+−Can I get just the sizes I need?
Yes. Each platform group has checkboxes — uncheck the ones you don't need. The ZIP only includes what you selected.
+−What source resolution should I start with?
The largest output here is 2560×1440 (YouTube banner), so a 2560+ wide source ensures every size is sharp without upscaling. If you start smaller, the bigger sizes will be slightly soft — but most platforms re-encode anyway, so it's usually fine.
+−Are the sizes up-to-date for 2026?
Yes. These are the recommended dimensions for 2025-2026 across each platform's native uploader. Each platform's uploader will accept slightly different sizes too, but these are the ones that fill the frame correctly without unwanted cropping or stretching.
