Frequently Asked Questions
Common queries regarding client-side PDF image replacement.
Q.Will replacement compromise document layout?
No. The tool directly replaces underlying image streams. Text blocks, annotations, vector styling, and metadata coordinates are preserved perfectly.
Q.What image formats are supported for replacement?
You can upload PNG, JPEG, JPG, and WEBP files. The tool automatically transcodes them into compliant PDF image streams.
Q.Can I choose specific scaling settings?
Yes. You can choose to stretch the new image to fit the original boundaries or preserve the aspect ratio of your new image.
Q.What if no images are found?
Make sure your PDF contains actual embedded image assets. Some documents contain only vector shapes (lines/colors) which cannot be replaced as standard bitmap images.
