Prepare WordPress Thumbnail assets without guessing
The page starts from Pictobank’s current WordPress Thumbnail configuration and explains where the platform may still crop or reinterpret the file.
- 01
Add one image or a batch
Choose supported static files for the default WordPress cropped thumbnail. Pictobank inspects each source independently.
- 02
Review the prediction
Check the 150×150 FILL result, crop or padding behavior, and enlargement boundary per file.
- 03
Resize and download
Apply the visible configuration in the browser, then download the completed selected output.
Intent-specific guidance
WordPress Thumbnail sizing and framing guidance
Center the subject because the default derivative is a small square crop.
The 150×150 target uses a 1:1 frame. Fill determines whether mismatched sources are contained, cropped, padded, or distorted.
What Fill does here
The output covers the target frame with a centered proportional crop.
No-enlargement behavior
A source that is too small remains below the target, and the predicted dimensions are shown before processing.
Resize behavior
The page starts with FILL
The four choices below map directly to Pictobank’s canonical browser resize geometry.
Keep the whole image
Preserves proportions and keeps the complete source inside the target boundary.
Cover the frame
Preserves proportions and crops centered excess so the target is completely covered.
Add a frame
Keeps the complete image inside an exact canvas with transparent or white space.
Force exact edges
Changes source proportions to meet both target dimensions without crop or padding.
Accurate limitations
Boundaries stated before processing
No zero-loss promise, no hidden enlargement claim, and no assumption that every browser or destination accepts every format.
Site owners can change the WordPress thumbnail dimensions in Media settings.
The public embedded workflow accepts up to 30 static images and 100 MB per file; device memory can impose a lower practical boundary.
Browser canvas export is sRGB and does not preserve the source file’s original embedded metadata.

FAQ
WordPress Thumbnail resize questions
What configuration does WordPress Thumbnail load?
It opens with 150×150, Fill, enlargement prevented, and JPEG output.
Will every output have the exact target dimensions?
Only when the source is large enough for the selected policy. Undersized files remain smaller while enlargement is off.
Can several source sizes be processed together?
Yes. Each selected image is inspected and predicted independently; the batch never assumes every file matches its first image.
Are filenames or image pixels sent to analytics?
No. Analytics contain page-level and aggregate outcome data, not filenames, image bytes, source dimensions, object URLs, or signed URLs.
