How to merge images and PDFs into one document
Whether you are assembling a proof packet, combining scanned receipts, or bundling product photos with a spec sheet, this tool stitches every file into a single PDF while respecting the sequence you choose. Pick an export page size (or match each file), choose Fit to page or Real size, keep orientation unified when you want a clean print stack, then download one merged PDF ready for email, print, or upload to our complimentary file uploader.
Perfect for these workflows
- One print-ready Letter PDF from mixed phone photos and PDF proofs.
- Client approval packets where every page is portrait (or every page landscape).
- Insurance or real-estate bundles combining scanned pages and phone photos.
- Portfolio decks that interleave vector PDF spreads with WebP mockups.
Export size, fit, and orientation
Standard paper (default) places every image and every PDF page onto the same canvas: Letter, Legal, 11×17, 12×18, A4, half/quarter letter, postcards, or business card. Fit to page scales content to sit inside without cropping. Real size places images at pixels ÷ DPI (and PDF pages at their true size), then scales down only if they would overflow. Keep all pages the same orientation is on by default and can Auto-pick majority portrait/landscape, or force one direction.
Proof marks for client approvals
Turn on Proof marks when you need a merged PDF that shows where bindery will cut and where type should stay safe. A guide page is added first explaining every line. The overlays match our free bleed & safe zone visualizer. Choose Specify trim size for standard bleed files, or Bleed already in artwork when the image edge is the bleed boundary and the cut sits 0.125" inside. Marks are vector overlays - they do not recompress JPG or PNG data.
Quality settings explained
PDF pages are embedded onto your export canvas without unnecessary rasterization whenever the browser can read the source. JPEG and PNG images are embedded using their original compressed streams. For WebP, GIF, BMP, and similar formats, the tool decodes once and embeds a lossless PNG page so nothing is double-compressed.
The DPI control maps pixel dimensions to physical size for Match each file and for Real size placement. Use 300 DPI when you plan to send the merged PDF to a commercial printer such as our color copy or flyer printing services.

Frequently asked questions
How do I merge multiple JPG files into one PDF online?
Select or drop your JPG files, arrange them in the queue, and click Merge into PDF. Each image becomes one PDF page at full JPEG quality.
Can I merge PNG, WebP, and PDF files together?
Yes. Mix any supported image type with PDF documents. On Standard or Custom page size, every PDF page is placed onto your chosen export canvas (Fit or Real size). Images embed at full resolution.
How do I make every page the same orientation?
Leave Keep all pages the same orientation checked (it is on by default). Choose Auto to follow the majority of your files, or force Portrait / Landscape. Files that do not match are rotated counter-clockwise 90° onto the export page.
What is Fit to page vs Real size?
Fit to page scales each file to sit inside the export page without cropping. Real size places images using pixels ÷ DPI (and PDF pages at their true size), then scales down only if they would overflow the page.
Does merge order follow upload order?
Yes. Files appear in the queue in the order you add them. Drag rows or use the arrow buttons to change order before merging.
Are my files uploaded to your servers?
No file content is uploaded for merging. Processing runs locally in your browser. Only lightweight anti-abuse metadata is sent after a successful merge.
What is the page limit?
The merged PDF can contain up to 200 pages total, counting every page from multi-page PDF inputs plus one page per image.
Can I merge password-protected PDFs?
Encrypted PDFs cannot be merged in-browser. Remove the password first or send the files to our team via the complimentary file upload service.
How is this different from paid PDF merge tools?
Many paid services watermark free exports or downsample images. This tool keeps JPG and PNG at original quality and copies PDF pages without forcing a subscription.
Can I add bleed, trim, and safe zone proof marks?
Yes. Enable Proof marks (optional) before merging. A guide page is inserted first explaining every overlay. Every image page and every page from PDF inputs gets vector marks - blue dashed bleed edge, red trim line, green dashed safe zone, and black crop marks. Choose Specify trim size when your file includes bleed beyond trim, or Bleed already in artwork when the cut goes bleed distance inside the image edge.
