Processing method
Image output depends on source dimensions, file format, compression quality, and transparency. Photos, logos, and text-heavy graphics can react differently to the same setting, so review both pixel dimensions and visible quality.
How files and inputs are handled
Core processing runs in the current browser whenever possible. OneClickTool does not store original files or tool inputs on its own server. Review the preview and output values before downloading or submitting an important result.
Frequently Asked Questions
Can I make both 4:5 feed and 9:16 story images?
Yes. Select 1:1, 4:5, 3:4, or 9:16 presets from the same uploaded image.
Can I fit the image without cropping?
Use contain mode to keep the whole image visible with padding. Cover mode fills the frame and may crop.
Is this an official Instagram tool?
No. OneClickTool is an independent tool for preparing images before upload.
