Images to PDF Converter — Merge JPG & PNG into One PDF

Merge JPG, PNG, HEIC, WebP and other images from URLs into one PDF (or one PDF per image): A4, Letter or fit-to-image pages, margins, auto-rotation, compression. Download link per PDF. $0.022 for a 10-image PDF.

Merge images into a PDF online, in bulk. Paste links to JPG, PNG, HEIC (iPhone), WebP, AVIF, GIF, TIFF or SVG images and get one PDF with one image per page, in the order of your list, with a direct download link. Pick A4, US Letter or fit-to-image pages; A4 and Letter pages turn portrait or landscape to match each image, which is centred inside your margin. Photos are rotated upright from their EXIF orientation and compressed as JPEG at the quality you choose, and screenshots, scans and graphics in PNG, GIF, TIFF or SVG are embedded losslessly so text stays sharp. Want one PDF per image instead (JPG to PDF, PNG to PDF)? Switch the mode. Optionally resize large photos first to keep the PDF small. Use it to turn photographed receipts, invoices, delivery notes and forms into a single PDF for accounting, insurance claims or archives, to bundle product or property photos into a PDF catalogue, to make a printable PDF from a gallery, or as an images-to-PDF step for Make, n8n, Zapier and AI agents. Pricing: $0.002 per page image + $0.002 per PDF, so a 10-image PDF costs $0.022 with no compute bill on top (other images-to-PDF actors charge up to $0.055 for the same 10 images). Failed images are never charged and simply leave no page.

What data does it return?

Every run outputs clean, schema-validated rows like these:

fileName	format	pageCount	originalBytes	outputBytes	sourceUrl
images.pdf	pdf	10	18634112	6120448	https://example.com/receipts/2026-10-01.jpg
00001-scan-page-1.pdf	pdf	1	412880	398112	https://example.com/scans/scan-page-1.png

How much does it cost?

Transparent pay-per-event pricing — you only pay for what you get, and the actor always respects your run budget: set a maximum total charge and it stops cleanly at the cap instead of overrunning.

Event	Price	Charged	Worked example
image-processed	$0.002	per image placed on a PDF page (orientation, resizing and compression included)	A 10-page PDF = 10 × $0.002 = $0.02 for the pages
pdf-created	$0.002	per PDF file created (each page image is also one image-processed)	10 images merged into one PDF = $0.02 + $0.002 = $0.022; 100 images into one PDF = $0.202; 10 images as 10 separate PDFs = $0.04
heic-decoded	$0.001	per HEIC/HEIF source image decoded (iPhone photos; added on top of image-processed)	An iPhone HEIC photo on a page = $0.002 + $0.001
large-image	$0.002	per source image over 25 megapixels (all frames count for kept animations; added on top of image-processed; up to 50 MP accepted)	A 36 MP camera photo = $0.002 + $0.002 = $0.004; a 12 MP phone photo has no add-on
apify-actor-start	$0.00005	per run per GB of memory (platform start fee)	One run at 1 GB = $0.00005

Input options

Field	Type	Required	Default	Description
imageUrls	array	yes	—	Direct links to the images, in page order (JPEG, PNG, HEIC/HEIF, WebP, AVIF, GIF, TIFF or SVG; the format is detected from the file itself). Up to 25 MB and 50 megapixels per image.
format	string	no	"pdf"	PDF (default) builds PDF files from your images. The other formats convert the images themselves (WebP, AVIF, JPEG, PNG) instead.
quality	integer	no	85	JPEG quality for photos inside the PDF: lower = smaller PDF. 85 (default) looks identical on screen and in print; 70 roughly halves the size. PNG, GIF, TIFF and SVG images are embedded losslessly.
width	integer	no	—	Optional: shrink images wider than this before putting them in the PDF (makes the PDF much smaller; 2000 px is plenty for A4). Empty = keep the original size. Image pixels are never upscaled (fitting to the PDF page is separate).
height	integer	no	—	Resize so the image is at most this tall. Empty = keep the original height.
fit	string	no	"inside"	When both width and height are set: 'inside' keeps the aspect ratio within the box, 'cover' crops to fill the box exactly, 'contain' pads to the box with the background colour.
background	string	no	"#ffffff"	Hex colour used for padding ('contain') and for transparent areas when converting to JPEG.
stripMetadata	boolean	no	true	Remove EXIF, GPS location, camera details, XMP and IPTC from the output (photos are rotated upright first). Smaller files and no leaked locations. Each row still reports whether the original had EXIF / GPS.
maxFileSizeKb	number	no	—	Optional. Lowers the quality step by step (and, if needed, the dimensions) until each image fits under this size. Rows show the quality used and whether the target was met.
keepAnimation	boolean	no	true	Animated GIF or WebP converted to WebP keep all frames. Off = first frame only. AVIF, JPEG and PNG output always use the first frame.
outputMode	string	no	"links"	'Links' saves each image with its own download link. 'ZIP' bundles all images into ZIP files (up to 200 MB each; links in the OUTPUT record). 'Both' does both. A merged PDF is always a download link.
filenamePattern	string	no	"{index}-{name}"	Tokens: {index} (00001…), {name} (original file name), {width}, {height}, {format}. The extension is added automatically; duplicate names get a -2, -3… suffix.
maxImages	integer	no	1000	Stop after converting this many images.
pdfMode	string	no	"merge"	'Merge' puts all images into one PDF, one image per page, in the order of your list. 'Separate' makes one PDF per image.
pdfPageSize	string	no	"a4"	'Fit image' makes each page exactly the size of its image (96 dpi). A4 and Letter pages turn portrait or landscape to match each image, which is scaled to fill the page inside the margin.
pdfMarginMm	integer	no	10	White margin around the image on A4 and Letter pages. 'Fit image' pages have no margin.
pdfFileName	string	no	"images"	Name of the merged PDF (without .pdf). Very large merges are split into parts: name.pdf, name-part-2.pdf, ...

Limits & honest notes

• Input: direct image URLs, in page order. Images that fail to download or decode are reported as error rows (not charged) and leave no page; the PDF keeps the order of the rest.
• Each image can be up to 25 MB and 50 megapixels; sources over 25 MP add large-image ($0.002) and HEIC photos add heic-decoded ($0.001). Animated GIFs use the first frame.
• One image per page. 'Fit image' pages are the image size at 96 dpi; on A4/Letter pages images are scaled to fill the page inside the margin (small images are enlarged to fit).
• Photos are re-encoded as baseline JPEG at your quality setting (rotated upright, sRGB); PNG, GIF, TIFF and SVG are embedded as lossless PNG. Transparent areas in JPEG pages become the background colour.
• A merged PDF holds up to about 128 MB of images at 1 GB memory (more with more memory); bigger merges are split into name.pdf, name-part-2.pdf, and so on, and each part is one pdf-created.
• No OCR: the PDF contains images, not searchable text.
• Download links work for the lifetime of the run's storage (Apify's default retention for your plan). ZIP files are split into parts of up to 200 MB.
• Internal and private network addresses are always refused, including through redirects or DNS tricks. Only convert images you have the right to use.
• Respects your run budget: set a maximum total charge and the actor stops cleanly at the cap.
