Instagram creators use OnlineTools4Free to resize photos to the right dimensions, compress images for faster uploads, and create collages for carousel posts.
A step-by-step workflow tailored for Instagram users. No installations, no accounts — just open the tool and go.
Use the Image Resizer to create images at Instagram sizes: 1080x1080 for square posts, 1080x1350 for portrait posts, and 1080x566 for landscape posts. Exact dimensions prevent Instagram from cropping your content.
Large files take longer to upload and Instagram re-compresses everything anyway. Use our Image Compressor to bring file sizes down to 500KB-1MB for the smoothest upload experience.
Use the Collage Maker to combine multiple photos into a single image for carousel posts. This lets you show more content in each swipeable card.
If your iPhone saves photos in HEIC format, convert them to JPG using our HEIC to JPG converter before editing or uploading. HEIC is not universally supported by editing tools.
Upload a reference photo to our Color Palette from Image tool to extract its dominant colors. Use these colors to maintain a consistent visual theme across your Instagram feed.
These tools are the most useful for Instagram users. All free, all browser-based.
No account, no plugins, no setup. Open the tool, process your file, use the result in Instagram.
