Instagram photo resizer for social media

This Instagram photo resizer also covers Facebook, LinkedIn, TikTok and 4 more platforms: upload an image, choose a platform and post type — an Instagram feed post, a Facebook cover photo, a LinkedIn link preview, a TikTok video cover, and more — and it resizes the photo to that platform’s real published pixel dimensions using the Canvas API. It cover-crops from the center so the exact target frame is filled with no empty bars, then offers the result as a direct download. Nothing you upload ever leaves your browser.

Image resizer FAQ

Does this tool upload my image anywhere?
No — every resize happens locally in your browser using the Canvas API, and nothing is uploaded to a server.
What does cover-cropping mean?
The image is scaled so its shorter side fills the target frame, then the longer side is trimmed evenly from both edges so nothing looks stretched.
Which platforms does the resizer cover?
Instagram, Facebook, LinkedIn, TikTok, X, YouTube, Pinterest and Bluesky, each sized to that platform’s own current published dimensions.
Can I resize a PNG and keep its transparency?
Yes, choose PNG as the output format and any transparent areas in the original image stay intact.
Will resizing reduce my image’s file size?
Often yes, since the output is usually smaller in pixel dimensions than the original, though the exact result depends on the format you choose.
Does the tool ever add empty bars around my image?
No — it always cover-crops to fill the exact target frame completely, so there are never empty bars or letterboxing.
Can I use this on a phone?
Yes, the resizer runs entirely in your mobile browser using the same Canvas API it uses on desktop.
