PNG files are often used for screenshots, diagrams, and graphics with transparency. Turning them into a PDF can make a collection easier to send or review as a document. ERITHRA embeds one PNG on each page without first asking you to convert the pictures to JPEG.
Assemble the graphics
Choose the PNG files in the intended reading order. You can use up to 20 images, with a 20 MB and 40 megapixel limit for each. Check the file list carefully when names are similar or when a folder includes both working drafts and final graphics.
Select Create PDF. Each image fills a page sized from its own width and height. There is no standard-paper preset, page-margin field, or automatic layout of several images on one sheet. If the images have different proportions, the PDF will contain differently shaped pages.
PNG transparency is retained in the embedded image. A normal PDF viewer may display the page against white, so a white-looking background does not necessarily mean the source transparency was replaced. Inspect the result in the actual workflow that needs it.
Follow a two-page example
Suppose you select a 1000 by 600 PNG diagram followed by a 600 by 1000 PNG screenshot. The output contains two pages, in that order. Their page canvases measure 1000 by 600 points and 600 by 1000 points, with each image drawn across its respective canvas.
The conversion does not make both pages A4 or force them into a shared landscape template. If you need standard physical dimensions, prepare the artwork accordingly or use a document layout application with explicit paper-size controls. Always check print preview before making a paper packet.
Open the saved PDF and verify that text inside the screenshots is legible. Text that exists only as pixels in the source image remains image content. Creating the PDF does not add searchable text or recover clipped information at the edges.
Keep a usable source collection
All processing remains in your browser. Preserve the original PNGs if you may need to edit the diagrams, change ordering, or produce another format later. A PDF wrapper does not make a screenshot’s private contents safe to disclose; review the visible material before sharing.
If an image fails, confirm that it is a genuine supported PNG and within the pixel limit. An oversized screenshot may need preparation before assembly. Use PDF Page Reorder to change the finished sequence, or JPG to PDF when the source collection consists of JPEG photographs rather than PNG graphics.
