Most people encounter PDF problems in the same handful of ways: a document that's too large to email, several scanned pages that need to become one file, a multi-hundred-page report where you only need a specific section, or a PDF you need to turn into images for use elsewhere. Each of these has a straightforward solution, and Portimg's PDF tools handle all of them in the browser without any software to install or account to create.
This is an overview of what each tool does and when you'd actually reach for it.
Merging images into a PDF
If you have a collection of photos, scans, or images that need to become a single document, the image to PDF tool combines them in whatever order you arrange them and outputs a single PDF. The common use cases are submitting scanned assignments or application documents as one file, creating a portfolio from separate image files, or consolidating a set of photographed receipts for expense reporting.
File naming helps here: if you're uploading a batch and order matters, naming files numerically before uploading (01.jpg, 02.jpg, and so on) keeps pages in the correct sequence. Use the highest resolution images you have — the PDF output quality reflects whatever you put in.
Splitting a PDF
The split tool extracts specific pages from a larger PDF, which is useful in a few distinct situations. You might need to pull a single chapter from a long report to share with someone who doesn't need the full document. You might need to separate a combined form into individual sections. Or you might have a PDF where a few pages are relevant and the rest isn't — splitting lets you isolate exactly what you need rather than sending or storing the entire file.
You select which pages to extract, and the tool produces a new PDF containing just those pages. The original file is unaffected.
Compressing a PDF
PDFs created from high-resolution scans or image-heavy documents can grow very large — large enough to hit email attachment limits, fail to upload to web forms, or be slow to open on a mobile connection. The compression tool reduces file size by optimising the embedded images and removing redundant data, usually without a noticeable change in visual quality for everyday documents.
How much compression you get depends on the source material. A PDF made from high-DPI scanned photos will compress significantly. A PDF that's already mostly text with minimal images has less room to shrink. The tool shows you the output file size before you download, so you can assess whether it meets your needs.
Converting PDF pages to images
The PDF to image converter turns each page of a PDF into a separate image file. This is most useful when you need the content of a PDF in a format that accepts images rather than documents — social media posts, presentation slides, web pages, or image editing tools. It's also the first step for running a scanned PDF through OCR, since the OCR tool works on images rather than PDF files directly.
Output is typically JPEG or PNG depending on what the tool produces. PNG preserves more detail for text-heavy pages; JPEG is generally smaller for photo-heavy content.
Merging multiple PDFs
The PDF merge tool combines separate PDF files into one. This comes up when you've created documents in separate stages that need to be submitted or sent together: a cover letter and a resume, an application form and supporting documents, a report and its appendices. Rather than sending multiple attachments, you merge them into a single file the recipient can open and navigate without managing several documents.
Arrange the files in the order you want the pages to appear before uploading, and the tool combines them in that sequence.
A note on file privacy
All tools in the toolkit process files server-side and delete them immediately after you download the result. Nothing is stored, and no account is linked to your uploads. For sensitive documents — contracts, personal records, financial files — it's worth knowing this before you upload, and it's the reason the tools are designed this way.
If you regularly work with PDFs and find yourself bouncing between different websites for different tasks, having the toolkit bookmarked means the right tool is always a click away rather than a search.
