What Instagram image sizes does this tool support?

Square (1080×1080 px), Portrait (1080×1350 px), Landscape (1080×566 px), and Stories/Reels (1080×1920 px). These match Instagram's official recommended dimensions for every major post type.

What is the difference between Fit, Fill, and Stretch?

Fit scales your image to fit entirely inside the frame with no cropping, but background bars appear where the image doesn't reach. Fill scales the image to cover the entire frame and lets you pan and zoom to choose which part to keep — no black bars. Stretch distorts the image to exactly fill the frame, which may alter its proportions.

How do I resize an image for Instagram without black bars?

Use Fill mode to cover the entire frame with no black bars. Drag to pan and scroll to zoom so you can choose exactly which part of your image to keep. Alternatively, use Fit mode with the Blur background option — it fills the background with a blurred version of your photo instead of solid bars.

Which resize mode should I use for Instagram?

Fill is best for most photos — it fills the frame with no gaps and lets you control the crop. Use Fit when you need to show the full image without any cropping. Stretch is rarely recommended unless you intentionally want the distortion effect.

What does the Blur background do?

The Blur option fills the background with a blurred, stretched version of your own image. This creates a cohesive, polished look popular on Instagram — especially useful in Fit mode where solid color bars would otherwise appear.

Does this tool add a watermark?

No. This tool never adds a watermark, logo, or any overlay to your image. What you see in the preview is exactly what you download.

Is my image uploaded to your servers?

No. All processing happens entirely in your browser using the Canvas API. Your image is never uploaded to any server, ensuring complete privacy.

Does this tool compress my image?

JPEG output uses 92% quality, which is visually lossless for most photos. For fully lossless output, choose PNG format.
