Why this size
Image converter to PDF: one file from many images
Forms, offices and email often want documents as one PDF, not a pile of photos. This converter places each image on its own page, scaled to fit A4 or Letter with even margins, or at the image's own size if you choose Fit.
If the form sets a size limit, type it before you download, for example 250 KB. The converter builds the PDF and compresses the pages only as much as needed to stay under it. For common limits there is a page with the size already set: under 50 KB, 200 KB, 400 KB, 500 KB and 1 MB. Already have a PDF that is too big? Add it here and type the limit: the photos inside are compressed while typed text stays text. You can add photos to go with it, and everything becomes one PDF.

How the tool works
Each image becomes one page of a PDF built in your browser, and a PDF you add keeps all its pages, in the order you add the files. With a size limit, the tool first compresses the photos inside the PDF, quality first and size second, while typed text, links and drawings stay as they are, so the text can still be selected. Only if that is not enough is each page drawn with pdf.js (Mozilla, Apache 2.0) and saved as an image, smaller pages before lower quality, until the whole file is under the limit. Nothing is uploaded. Everything happens in your browser; your images are never uploaded.
