Will my images lose quality when converted to PDF?

No — FlowPDF embeds your images in the PDF at their original resolution and quality. The PDF acts as a container, not a converter. This means your images stay exactly as they were, with no compression artifacts or quality loss. The PDF's file size will be roughly the sum of the original image sizes (plus small PDF overhead), so you're not getting a compressed version of your photos unless you specifically request compression.

Can I control the page size and orientation of the PDF?

Yes — you can specify the page size and orientation in your instruction. For example, say 'create a PDF with A4 portrait pages' or 'make it Letter landscape.' If you don't specify, FlowPDF uses the image's own aspect ratio to determine the page size, with a default of A4 if images have varied dimensions. You can also request that all pages be the same size even if images have different proportions.

How does the tool handle images with different dimensions and orientations?

FlowPDF adjusts each image to fit within the selected page size while preserving the aspect ratio of the original image. If a horizontal image is placed on a vertical page, the tool adds margins on the top and bottom to keep the full image visible without cropping. If a vertical image is placed on a horizontal page, margins are added on the sides. You can also specify whether you want images to fill the page (which might crop the image) or fit within the page (which adds margins).

Can I combine images and existing PDFs in one document?

Yes — you can upload a mix of images and PDFs, and FlowPDF will merge them into a single PDF. For example, you could upload 'cover.jpg,' 'contents.pdf,' and 'appendix.png' and get one PDF with all content in order. This is a powerful feature for creating comprehensive documents from mixed sources without using multiple tools.

Can I add text or annotations to the images during conversion?

The basic images-to-pdf tool creates a PDF with the images as-is. If you need to add text (like captions or page numbers) or annotations to the image pages, you can use the add_header_footer, add_page_numbers, or watermark_pdf tools after the initial PDF is created. This two-step approach gives you full control over the final document.

Convert Images to PDF Online — JPG, PNG, BMP, GIF, Free, No Sign-Up

You have a collection of images — photos from a meeting, scanned receipts, screenshots of web pages, or artwork for a portfolio — and you need them in a single PDF. Maybe it's for a client presentation, a photo book, or a scan of a multi-page document that came as separate JPGs. FlowPDF combines all your images into one PDF, with each image on its own page, in the order you specify. The conversion is lossless where possible — images are embedded at their original resolution, so your PDF preserves the visual quality of the originals. You can upload a mix of image formats (JPG, PNG, BMP, GIF, WebP, TIFF) and FlowPDF handles each one correctly. This is the easiest way to turn scattered images into a organized, shareable document that anyone can open on any device, with no software required. Whether you're converting a batch of slides, a photo album, or a multi-page scan, FlowPDF makes the process seamless.

Frequently asked questions

FlowPDF supports all common image formats: JPEG/JPG, PNG, BMP, GIF, TIFF, WebP, and SVG (as rasterized images). If an image is in an unsupported format, FlowPDF will alert you during upload. The supported formats cover virtually all use cases — phone photos (JPEG/HEIC), screenshots (PNG), scanned documents (JPEG/PNG), and web graphics (WebP).
