How to Insert Image Into PDF
Adding a logo to a cover page, inserting a signature image on a contract, placing a photo in a report, or adding a QR code for quick access—these are everyday tasks that require placing images precisely onto existing PDF pages. SublimePDF lets you insert images at exact positions with control over size, rotation, opacity, and layering relative to existing content.

Upload your PDF
Open the Insert Image tool and upload the document where you need to place an image. Navigate to the page where the image should appear.
Upload the image
Click 'Insert Image' and select a JPG, PNG, SVG, or WebP file from your device. PNG images with transparency are fully supported—perfect for logos and watermarks that need to blend with the page.
Position and resize
The image appears on the page with drag handles. Move it to the exact position by dragging, and resize by pulling corner handles (hold Shift to maintain aspect ratio). Use the alignment guides to center or align with margins.
Adjust image properties
Set the opacity (lower for watermarks, full for photos), rotation angle, and layer order (in front of or behind existing content). For signature images, positioning behind text makes the signature appear naturally on the signing line.
Insert on more pages if needed
To place the same image on multiple pages (like a logo on every page), use the 'Apply to page range' option. Specify all pages, odd pages only, even pages only, or a custom range. The image appears at the same position on each selected page.
Pro Tips
- 💡 For signature images, use a PNG with a transparent background so the signing line shows through naturally.
- 💡 When inserting logos on every page, position it once on the first page, then apply to all pages—the tool copies the exact position and size.
- 💡 To add a QR code, generate it as a PNG at 200×200px or larger, then insert it. Smaller QR codes may not scan reliably when printed.
- 💡 If the image appears behind existing content and you can't see it, change the layer order to 'In front of content' in the image properties panel.

How to Insert Pages Into PDF
When assembling documents, you frequently need to insert additional pages at specific positions—adding a signed page into a contract, inserting an appendix before the references section, or adding a new chapter between existing ones. Unlike merging, which appends files end-to-end, inserting lets you place pages precisely where they belong within an existing document.
