What this tool does
Resizes your photos to the exact dimensions recommended by Instagram to reduce awkward auto-cropping. Platforms may still recompress after upload. It helps you crop images to fit feed or stories layouts.
Trust and privacy are built into the workflow. Nothing leaves your device during processing, and there is no account setup. That makes it suitable for personal photos, client assets, product shots, and everyday creative work.
How to use Instagram
- Upload or drag your file into the tool above.
- Choose output settings such as quality, size, or page options.
- Preview the result before you download.
- Download the finished file for web, email, print, or sharing.
Tip: start with balanced quality settings rather than maximum compression so detail stays intact for web and sharing.
Key benefits
- Use 4:5 aspect ratio (1080x1350) for maximum screen real estate in the feed
- Stories and Reels should be 1080x1920 pixels (9:16)
- Square posts (1080x1080) are classic but take up less space than portrait
- We apply high-quality sharpening automatically to prevent blurriness
Privacy note: no files leave your device. All convert steps run locally in your browser.
