Page size, resolution, ordering, compression, and privacy decisions when building PDFs from PNG, JPG, WebP, and SVG in-browser.
Prepare sources first
Check orientation, crop, and readability before selecting images. Angled phone scans, shadows, and desk backgrounds reduce useful document area. Consistent orientation and contrast produce a more coherent PDF.
Sequential names such as 01-cover and 02-form help the file picker preserve order, but always review the visible list.
A4 or image-sized pages?
Automatic A4 orientation is predictable for printing. Using landscape for wide images avoids excessive reduction. Margins protect against printer clipping but can make tiny text smaller.
Image-sized pages preserve pixel aspect ratio and work for screenshot archives. Mixed source resolutions can create inconsistent physical page sizes, so A4 is usually more predictable for print.
Balance size and performance
Large images increase browser memory and PDF bytes quickly. If a 12-megapixel source only needs readable document text, reducing the longest edge first can help. Small type, barcodes, and fine lines require care because aggressive compression can remove information.
ByteQuant reports real before-and-after bytes. Inspect a representative page at the intended zoom, and never replace the archival source with a lossy derivative.
Privacy, rights, and final review
Receipts, IDs, and contracts can contain personal data. Local generation reduces unnecessary upload, but downloads, backups, and sharing channels still matter. Process only documents you are authorized to use.
After creation, verify page count, order, orientation, clipping, and readability. Image conversion is not OCR and does not make text searchable or authenticated. Apply the relevant institutional document standard for official delivery.
