Image Tools questions
Resize Image: Can resizing make a small image sharp?
No. Enlargement can smooth pixels but cannot recreate genuine missing detail.
Resize Image: Should width and height both be entered?
Lock the aspect ratio and set one dimension unless an exact, potentially cropped shape is required.
Crop Image: Does cropping reduce quality?
The selected pixels are preserved, but exporting to a lossy format can add compression.
Crop Image: Which aspect ratio should I use?
Use the ratio required by the destination; choose Free when no fixed ratio is required.
Compress Image: What quality should I choose?
Start near 80–85 for a JPEG photograph, inspect the preview, and lower it gradually.
Compress Image: Will dimensions change?
Compression does not need to change dimensions; use Resize Image when pixel dimensions are also too large.
Convert Image: Which format is best for photos?
JPEG is broadly compatible; WebP often produces smaller web files at comparable visual quality.
Convert Image: Why did transparency disappear?
The selected output format may not support transparency, or a background colour was applied during export.
Blur Image: Is blur safe for confidential redaction?
Not necessarily. Permanent opaque redaction is safer when information must be unrecoverable.
Blur Image: Why do image edges look dark?
Some kernels sample beyond the boundary; edge-aware handling or cropping can reduce the artifact.
Passport Photo Maker: Does a green preview guarantee acceptance?
No. It indicates measurable layout checks only, not every official or human review criterion.
Passport Photo Maker: Can I digitally change the background?
Some authorities permit a plain replacement while others restrict editing; check the current official instructions.
Text to Image: Will the image text be selectable?
No. The export contains pixels, so keep a text version for accessibility and search.
Text to Image: Which format should I export?
PNG suits sharp text; JPEG may create halos but can be smaller for textured backgrounds.
Remove Background: Why are fine edges missing?
Low contrast and semi-transparent detail are difficult to classify; a cleaner source or manual mask may be needed.
Remove Background: Which format keeps transparency?
PNG is the broadest compatible choice; WebP can also preserve alpha transparency.
