About Social Image Resizer
Every platform wants a different size — square and portrait Instagram posts, 9:16 stories, wide Facebook and LinkedIn covers, YouTube thumbnails and banners. Pick the platform and format and the picture is cut to exactly the right pixels.
Smart crop keeps the interesting part in the frame, or choose an anchor; or fit the whole picture on a blurred copy of itself, the look used for stories and reels. Save as JPG, PNG or WebP, in a batch, privately in your browser.
Good for
- Posting photos on Instagram, Facebook and LinkedIn without awkward crops
- Making YouTube thumbnails and channel art
- Creating covers, banners and profile pictures
Tip: For stories and reels, choose “Fit inside” with the blurred background — nothing gets cut off.
Frequently asked questions
Which sizes are included?
Posts, stories, covers, banners, thumbnails and profile pictures for Instagram, Facebook, X (Twitter), LinkedIn, YouTube, TikTok, Pinterest, WhatsApp, Telegram, Snapchat and Threads, plus Open Graph and email headers.
Crop or fit — which should I use?
Crop to fill uses the whole frame and suits photos; smart crop keeps the subject in view. Fit with a blurred background shows the whole picture with no cropping — popular for stories and reels.
Why do my pictures look blurry on social media?
Platforms shrink and re-compress uploads that are too big or the wrong shape. Uploading the exact recommended size avoids that.
Can I make several sizes from one picture?
Yes — convert once per preset, or add several pictures and resize them all to the same preset.
Are my images uploaded?
No. Resizing happens entirely in your browser — your pictures never leave your device.
