PRESETS AND FEATURES

AVOID THESE MISTAKES
Stretching a photo to force a ratio.
Use a preset that adds letterboxing or repositions the crop, instead of distorting the image.
Resizing after already compressing the file.
Resize from the original, full quality photo, then compress once at the end.
Ignoring the edges when there is text or a logo.
Keep key content centered before resizing, since edges are the first thing a crop removes.

SCHEDULING
Plan and publish your resized photos without leaving the app.
An instagram post resizer is a tool that adjusts an image’s width and height to match Instagram’s supported aspect ratios: 1:1, 4:5, or 1.91:1. It does this without distorting the photo or cropping out the subject.
No. Resizing to a supported aspect ratio does not reduce quality on its own. Quality loss comes from compression, not from changing dimensions. A photo resized to 1080×1080 stays sharp, as long as the original file was high resolution to begin with.
Yes. Resizing an image is free and does not require an account. No watermark on the download, and no daily limit.
JPG, PNG, and WEBP for upload. The resized image exports in the same format it was uploaded in. HEIC files from iPhones may need to be converted to JPG first.
Yes. Batch resize lets you upload several images together and resize them all to the same aspect ratio in one pass. Useful for carousel posts or grid layouts where every image needs to match.
4:5 portrait is generally the strongest choice for feed posts, since it takes up more vertical space than a square post. Square (1:1) is still the safest pick for a uniform grid look.
No. Processing happens in your browser rather than on a remote server, so nothing is retained after the session ends.
Upload a photo, pick a ratio, download in seconds. No account, no watermark, no cost.
