📱Social Media Image Resizer

One photo, every social size

Every network wants a different shape. Instagram feed posts are 1080×1080 or 1080×1350, Stories are 1080×1920, a YouTube thumbnail is 1280×720 and a Facebook page cover is 820×312. Resizing the same product shot six times in a photo editor eats an hour per campaign, and it is easy to export the wrong one. The Social Media Image Resizer holds all of those sizes as presets, lets you tick as many as you need, and produces every version in one pass.

How it works

1. Drop one image or a whole folder. Batch mode processes up to 200 files.
2. Tick the presets you need. They are grouped by network: Instagram, Facebook, YouTube, LinkedIn, Pinterest, X, TikTok and WhatsApp. Selecting a network header ticks all of its sizes.
3. Choose a fit mode. Cover fills the frame and crops the overflow, Pad keeps the whole picture on a solid colour, and Blur fill keeps the whole picture over a blurred, enlarged copy of itself, the look used on many stories.
4. Pick output format and quality, then click Resize. Each result is named after the source plus the preset, for example mug-ig-story.jpg.
5. Download individually or as one ZIP.

Why it matters

Networks re-encode whatever you upload, and they do it best when the file already matches the display size. Uploading a 4000×3000 photo into a 1080×1350 slot means their servers crop it for you, often straight through the product. Uploading exactly the right size keeps your framing.

Twenty-one presets are built in. A few numbers worth remembering: the Instagram portrait post size at 4:5 takes up about 25% more screen than a square post, a YouTube thumbnail must be at least 640 px wide and under 2 MB, and a Pinterest pin at 2:3 avoids the cropping that longer pins receive in the feed.

For marketplace listing sizes, such as Amazon's 2000×2000 white main image or Etsy's 2000×1500 listing photo, use the Marketplace Preset Resizer instead. The TikTok Shop 9:16 video cover matches the TikTok preset here exactly.

Tips

• Keep text and logos away from the top and bottom 250 px of story images. Instagram and WhatsApp overlay the profile bar and reply box there.
• For a page cover or channel banner, use Cover fit and check the preview; those are the presets where the crop is most aggressive.
• Use Blur fill for portrait product shots going into a landscape slot, so the whole item shows without plain white bars.
• Add captions or a price after resizing with the Text on Image / Caption Tool, and split a wide image into a swipeable set with the Image Splitter.
• If the automatic crop cuts through the product, crop by hand first with the Image Cropper.

Privacy

Your images never leave your browser. Every resize is done with the Canvas API on your device and the ZIP is built locally, so nothing is uploaded and there is nothing to delete afterwards.
