What size should an Instagram post image be?

Instagram recommends 1080 x 1080 pixels for square posts. Portrait posts perform best at 1080 x 1350. Stories and Reels should be 1080 x 1920. Filagram includes all these presets.

Will resizing make my image blurry?

Enlarging a small image beyond its original dimensions can cause blurriness. Shrinking always produces sharp results. Start with the highest resolution source image you have.

What file formats are supported?

The resizer accepts PNG, JPG, and WEBP images. The output format matches your input. PNG stays PNG, so transparency is preserved.

Is my image uploaded anywhere?

No. The resize happens entirely in your browser using the Canvas API. Your image never leaves your device.

What is the passport photo preset?

The passport photo preset creates a 600 x 600 pixel image, corresponding to 2x2 inches at 300 DPI, the standard for most passport offices.
