How to use it
- Pick the Instagram size from the list. Defaults follow the table above.
- Drop your product photos, several at once (10 at a time for free).
- Choose how to fit: pad to keep the whole image, crop to fill the frame, or centre the product with empty edges trimmed.
- Choose the file type and the maximum file size, then press "Fit images".
- Download each image or everything as a ZIP. Nothing is uploaded anywhere.
Instagram checklist
- 4:5 posts (1080x1350) take the most feed space inside the supported range.
- Stories at 9:16: keep about 250 px at top and bottom clear of the account name and reply bar.
- Put a landscape photo in a story with the padding (contain) mode and a matching colour.
- Use JPG for small files; Instagram recompresses anyway.
Good to know
- Centre product works on a plain solid or transparent background, such as a white sweep. On a real scene or a gradient it pads instead and tells you on the result.
- The size cap lowers JPG/WebP quality only as much as needed; the pixel size never changes. PNG cannot be compressed by quality.
- Your originals are untouched. Results are new files with EXIF and location data left out.
Frequently asked questions
What is the file-size limit for Instagram images?
The Instagram sizes in the table do not list a fixed file-size ceiling. You can still set your own maximum file size; the tool lowers JPG/WebP quality only as much as needed without changing the pixel size.
Where do these sizes come from, and how reliable are they?
Read from the platform's own help pages: Instagram post 1:1, Instagram post 4:5. Widely used values from seller guides or secondary sources, because the official page needs a login or does not publish the value: Instagram story 9:16. Sources: help.instagram.com. Last checked 2026-09-29. Sizes can change, so check your seller account before a big campaign.
Are my photos uploaded when I fit them for Instagram?
No. Fitting runs in your browser. Your originals are untouched, results are new files without EXIF or location data, and up to 10 images at a time are free.
