Resize Photos for Instagram, TikTok, and Marketplaces

Every platform has a different ratio. A photo that is not prepared will be cropped automatically and may lose important parts.

The common problem

Calculating ratios manually and cropping one by one is tedious, especially for a weekly content batch.

How the on-device tool helps

Choose a preset and the tool performs a center crop and high-quality resize. For custom needs, enter your own width and height.

Quick steps

1. Open the resize-crop tool on FotoEditAI.
2. Choose a photo from your device. It is not sent to a server.
3. Adjust the available options and compare before/after.
4. Download the result and keep the original file separately.

Tips for better results

• Use 4:5 for Instagram feed to take up more screen space.
• Keep the original before cropping.
• Check that important objects are not cut in the center.

When this tool fits

This tool is for anyone who wants a fast result without an account or an upload. All processing runs in the browser, so quality depends on the device and photo resolution. For best results, use the original file rather than a screenshot or a photo that has been compressed repeatedly.

Short case study

A social media manager prepares a weekly content batch. They convert photos to 4:5 for the feed and 9:16 for stories, making sure the product is not cut off in the middle.

Checklist before downloading

• Compare the result before and after at the 50% position.
• Check subject edges, hair, and small details at 100% zoom.
• Make sure product or skin colors have not shifted too far.
• Keep the original file so you can retry with different options.
• Choose the right format: PNG for transparency, JPG for a smaller file.

Conclusion

Resize Photos for Instagram, TikTok, and Marketplaces can be done directly in the browser without an account. Start from the original photo, use moderate settings, and inspect the result before saving. If the result is not right, retry with lower intensity or a brighter photo. A gradual approach usually gives a more natural result than one extreme setting.

Privacy

There is no photo upload endpoint. The AI model is downloaded once and cached on the device. Closing the tab clears the editing session. Read the privacy policy and AI policy.
