How to Combine JPG and PNG Images into One PDF

Which image formats can you add?

The converter accepts JPG and JPEG, PNG, WebP, GIF, BMP, HEIC, and HEIF input through its file picker. HEIC and HEIF files require the in-browser conversion step to succeed. Browser decoding support and the individual file can affect whether less common formats load correctly.

• ·Use JPG for photographs when a smaller source file matters.
• ·Use PNG for screenshots, diagrams, or text-heavy images where sharp edges matter.
• ·Treat animated images as still pages; the tool does not create an animated PDF.
• ·If HEIC or HEIF conversion fails, export the image as JPG or PNG on the source device and try again.

How to make one PDF from multiple images

1. 1Open the Image to PDF Converter and select all the images you want to include. Each image appears as an item in the working list.
2. 2Drag images into the correct order, make any crop, rotation, scan, or filter adjustments, and choose page size, orientation, margins, and quality.
3. 3Choose Convert to PDF. The converter creates one PDF with one page for each prepared image and downloads it to your device.

Which PDF page size should you choose?

• ·Fit to image sizes each PDF page around its source image. Choose this when preserving differing image proportions matters more than consistent paper dimensions.
• ·A4 creates pages using the common 210 × 297 mm paper ratio, suitable for many international document workflows.
• ·Letter creates pages using the 8.5 × 11 inch ratio common in the United States and Canada.
• ·Legal uses the longer 8.5 × 14 inch paper ratio.

Portrait, landscape, and automatic orientation affect how each image is fitted to the chosen page. Margins add whitespace around the image. Before converting a submission, confirm the recipient’s required paper size rather than assuming A4 or Letter.

How do order, crop, and scan adjustments work?

The image list determines the final page order. Dragging an item changes where its page appears in the PDF. Per-image controls can rotate or crop a source, and the smart scan workflow can select document corners, correct perspective, and apply a visual filter before PDF creation.

Will combining images reduce quality?

Quality depends on the source image, its prepared dimensions, the page layout, and the selected quality option. The compressed option re-encodes prepared images as JPEG using the tool’s 72 percent setting. Compression can reduce file size but may add artifacts around fine text and line art.

• ·Choose the original-quality option when legibility or image detail is more important than output size.
• ·Choose compression when a smaller PDF matters, then inspect small text and high-contrast edges at normal reading zoom.
• ·Avoid enlarging a low-resolution image and expecting additional detail; PDF conversion cannot restore detail missing from the source.

Practical ways to combine images as a PDF

• ·Put photographed receipt pages into one ordered expense document.
• ·Combine front and back scans of a document when the recipient requests one PDF.
• ·Turn screenshots or exported diagrams into a review packet with one image per page.
• ·Create a PDF from photographed notes after cropping and correcting each page’s perspective.

What are the limits and privacy details?

The converter does not impose a fixed application file-count or total-size limit. Practical capacity depends on the number and pixel dimensions of the images, transformations applied, available browser memory, and device performance. Large phone photos can consume much more working memory than their compressed file size suggests.

Image preparation and PDF generation run locally in the browser without an EditPDF AI application document-processing request. Some application assets may still load over the network. Browser extensions, the operating system, and the destination where you save or share the PDF remain outside that processing claim.
