How to use Social Media Image Resizer
- Add one or more JPEG, PNG or WebP images. Every image in the run uses the same frame.
- Choose a Target frame, or set Custom size and type a width and height.
- Choose Fill to cover the frame and crop the overflow, or Fit to keep the whole picture and pad the leftover space.
- Pick the output format and quality, then select Fit to frame and download the file or the ZIP.
Example: Social Media Image Resizer
Fit a landscape photo onto a square frame.
Options
- Target frame
- Square, portrait, story and widescreen sizes cover most placements. They are round, common numbers rather than a promise, because platforms change their guidance and can apply their own crop after upload.
- How to fit the frame
- Fill covers the frame with the picture and trims the sides that do not fit, taken evenly from left and right or top and bottom. Fit keeps every part of the picture and pads the remaining space with the pad color, so nothing is cut away.
- Pad color
- Used by Fit only, for the space the picture does not cover. White suits most feeds; pick the color of the surface the picture will sit on when you want the padding to blend in.
- Output format
- JPEG keeps photo files small, PNG is lossless and larger, and WebP often beats both for size. Choose the original format to leave the encoding family unchanged.

Fill and fit are different jobs
Fill starts from the frame and asks what has to be removed to cover it, so a wide photo loses its left and right edges. Fit starts from the picture and asks what has to be added to reach the frame, so nothing is lost but the extra space shows the pad color. For a feed that shows the whole frame at once, fill usually looks deliberate; for a picture whose edges matter, fit is the safer choice.
Why the listed sizes are generic
The frames here are common, round numbers: a square, a 4:5 portrait, a 9:16 story and two 16:9 widescreen sizes. They give a good starting canvas, and the custom fields cover anything else. Requirements change between apps and over time, so treat the produced pixel size as the fact this page can prove and confirm the rest at the destination.
Questions about Social Media Image Resizer
Will this guarantee my upload is accepted?
No. It produces a file at the pixel size you chose. A platform applies its own rules after upload and can crop it again, re-encode it or reject it, so check the current requirement on the platform you are posting to.
Why is part of my photo missing after Fill?
Fill covers the whole frame, which means the sides that do not match the frame shape are trimmed, evenly from the center outward. Switch to Fit when every part of the picture has to survive.
Why are there blank bars beside my picture after Fit?
Fit keeps the picture whole, so the space left over in the frame is padded with the pad color. A square photo placed on a story frame therefore gets bars above and below, not stretched pixels.
Does the tool enlarge a small image?
Yes, it reaches the frame size you asked for, and the result reports each picture that was enlarged. Enlarging cannot add detail, so start from the largest copy you have.
Can I resize a batch in one go?
Yes, up to 20 images per run with the same settings. Several results arrive as a ZIP; a single result downloads on its own. The preview shows the first image only.
