How to resize an image to 150x150
- Choose or drop your images above.
- Keep “Crop to fill” for an exact 150x150 result, or pick “Fit inside” to avoid cropping.
- Download the resized files individually or as a ZIP.
About 150x150 pixels
A 150x150 image is square, with an aspect ratio of 1:1, and holds 22,500 pixels in total. As a JPEG it usually lands between 2.5KB and 4.9KB, depending on the picture and the quality you choose.
Where 150x150 is used
A common thumbnail size in galleries, shop lists and content management systems.
- Use JPG for photos and PNG for graphics with text or transparency.
- A square crop keeps the centre of the photo, so frame the subject in the middle.
- Start from the largest original you have. Enlarging a small picture makes it look soft.
Crop to fill or fit inside?
Crop to fill always gives exactly 150x150 by trimming the edges that do not match the shape. Fit inside keeps the whole picture and scales it so neither side exceeds 150x150, which can leave one side shorter. For a typical 4:3 phone photo, crop to fill removes about 25% of the picture. A 3:2 camera photo loses about 33%, a 16:9 screenshot about 44%, and a square image about 0%.
Quality and format
Check the result before you upload
Open the finished file and check three things: the picture measures 150x150, the subject is not cut off, and the file is small enough for where you upload it. If a platform sets a size limit, run the result through the online compression tool or choose a limit such as 200KB.
A tip for this size
Use Crop to fill for a clean square, or Fit inside to keep the whole picture. Need another size? Try 152x152, 144x144, 167x167, the general image resizer, or browse every size preset.
Frequently asked questions
Why is my image not exactly 150x150?
You are probably using Fit inside, which never crops. Switch to Crop to fill for exact dimensions.
How big will a 150x150 file be?
As a JPEG, usually between 2.5KB and 4.9KB. Photos with lots of fine detail come out larger, and simple graphics smaller. Lower the quality for a smaller file.
Is 150x150 the right size for thumbnails and small product pictures?
It is a widely used size for thumbnails and small product pictures, but platforms and agencies change their rules. Check the current guidelines before you upload.
Will detail survive at 150x150?
At small sizes fine detail disappears. Crop in close on the main subject and use a simple, high-contrast picture for the best result.
