Can I resize without distorting the image?

Yes — enable the 'Lock Aspect Ratio' toggle to maintain proportions when you change one dimension.

What social media presets are available?

Instagram Post (1080×1080), Facebook Cover (851×315), YouTube Thumbnail (1280×720), and LinkedIn Banner (1584×396).

What's the maximum image size I can resize?

There's no strict limit, but very large images (over 30 MB) may take a few seconds to process.

Can I make an image larger (upscale) with this tool?

Yes, you can upscale images, but making an image larger than its original resolution will result in some blurriness since the extra pixels must be interpolated.

Will resizing change the image format?

No — the output format matches the input. Upload a JPG and you get a resized JPG. Upload a PNG and you get a resized PNG.

What pixel dimensions should I use for a website banner?

A standard full-width website header banner is typically 1920×600px to 1920×1080px depending on the design. For a blog post featured image, 1200×630px is ideal.

Why Use Image Resizer?

Every platform has different image size requirements — Instagram wants square 1080×1080px posts, YouTube needs 1280×720px thumbnails, and Facebook covers are 851×315px. Uploading the wrong size means the platform either crops your image unexpectedly or stretches it, ruining the composition. Resizing before uploading also reduces file size, which speeds up upload times and ensures your images render crisp and sharp on every device. Our built-in social media presets take the guesswork out of which size to use.
