Frequently asked questions
Which Instagram size gets the most space in the feed?
Portrait 1080×1350 (4:5) takes the most screen area in the feed. Square 1080×1080 is the safe default for grids.
Is it really free and private?
Yes. Everything runs in your browser with open-source code; nothing is uploaded. No account, no watermark, no file-size limit other than your device's memory.
Will resizing make my image blurry?
Making an image smaller keeps it sharp. Making it larger cannot invent detail: expect softness above about 150% of the original size.
Which format is the output?
The same as the input by default (JPG stays JPG). You can switch to JPG, PNG or WEBP in the options.
