Crop images for Instagram: 1:1, 4:5 and 16:9
Prepare an image with a fixed aspect ratio instead of stretching it. In Change image format, choose a preset, check cropping or fitting and save as JPG, PNG or WebP. Check the platform preview afterwards: a post and its profile-grid thumbnail may display differently.
The right toolsHow to get started
- 01
Open the original and choose the target ratio. Quick presets include 1:1 at 1,080 × 1,080 px, 4:5 at 1,080 × 1,350 px and 16:9 at 1,920 × 1,080 px. These are tool presets, not guarantees for every platform placement.
- 02
Cropping fills the frame but removes edge areas. Fitting keeps the entire image and adds space where needed. Keep important faces, text and logos away from the edges and inspect the preview.
- 03
Choose output deliberately: JPG for photos, PNG when transparency or crisp graphics matter, and WebP when the destination supports it. Enlarging cannot create missing detail. Download and review the file before publishing.

A worked example
Crop images for Instagram: 1:1, 4:5 and 16:9
A 4,000 × 3,000 px photo is 4:3. For 4:5, a centred 2,400 × 3,000 px crop scales to 1,080 × 1,350 px, removing 800 px from each side. Choose fitting rather than cropping to keep the whole scene. A 4,000 × 2,250 px crop would produce 16:9.
Frequently asked questions
Is aspect ratio the same as file format?
No. 4:5 describes width relative to height. JPG, PNG and WebP describe how the image is stored. A 4:5 image can be exported as JPG or PNG, for example.
Why can the profile thumbnail still look different?
Platforms can crop posts and preview grids differently and change their display rules. Your local file remains unchanged. Check the current platform preview and leave generous margins around important content.

An upload limit is about file size, not just page count. Inspect the original, remove unnecessary pages from a working copy and compare compression modes. A particular target size or percentage reduction is not achievable for every PDF.

A PDF can contain actual text, scanned images or both. Check whether text is selectable first. Extract existing text directly and use OCR for image pages. This avoids unnecessary recognition and makes output limitations clearer.
