Resize an Image for Instagram
Crop and resize images to Instagram's recommended dimensions.
Why pick Convertify for this?
Files stay on device
Convertify processes everything in your browser using JavaScript. Your file is never uploaded — confirm with DevTools → Network. That makes this safe for sensitive material like contracts, IDs, and financial documents.
No upload wait
Because nothing uploads, processing starts the instant you click. For typical files (under 50 MB) the whole job finishes in seconds — no progress bar, no queueing behind other users.
No daily quota
Free without limits, including no "3 conversions per day" cap that competing services impose. Run as many resize image jobs as you need.
No watermark
Your output is clean — no Convertify branding, no metadata stamp. Same as if you'd run a paid desktop app.
Frequently asked questions
What image size does Instagram use?⌄
Square posts are 1080x1080px, portrait posts 1080x1350px, stories and reels 1080x1920px, and profile pictures around 320x320px.
How do I resize an image for Instagram?⌄
Upload your photo, set the target dimensions for the post type, and download the correctly sized image.
Why does Instagram crop my photos?⌄
Instagram auto-crops images that don't match its aspect ratios. Resizing first ensures your whole image is shown as intended.
Will resizing reduce quality?⌄
Resizing to Instagram's recommended sizes keeps photos sharp. Avoid enlarging small images, which can look soft.
Is it private?⌄
Yes. Resizing runs in your browser, so your photos are never uploaded.
