Can I convert a PDF to JPG without uploading it?

Yes. The PDF to images tool renders each page in the browser and packages the results in a ZIP. The source PDF is not sent to a conversion server. You can pick JPG for small file size or PNG when you need lossless rendering, and choose a quality level appropriate to your use.

Do I lose quality when converting PDF to image?

You can choose. The standard quality is a good balance for most uses, including social posts and previews. For print or design work, pick the high or very high option, which produces a larger file with no visible artefacts. The original PDF is not changed — you can re-export at a different quality any time.

What is the difference between PDF to text and OCR?

PDF to text reads the selectable text layer that exists in digitally generated PDFs. OCR runs on image-only pages (scans) and recognises the text from the pixels. If you are not sure which one to use, open the PDF in any viewer and try to select a word with the mouse — if you can highlight it, use PDF to text; if you cannot, run OCR.

Can I extract text from a scanned PDF?

Yes, by running OCR first. OCR adds a text layer to the scanned pages, which PDF to text (and any other tool that relies on text selection, including search) can then read. The OCR tool runs entirely in the browser with Tesseract.js.

How do I reduce a PDF file size without losing too much quality?

Start with the recommended compression level. If the result is still too large, try the stronger level — image quality will drop a little, but text stays sharp. For scanned documents, the biggest win usually comes from re-OCRing at a lower DPI rather than re-compressing.

Convert PDF to and from other formats — without uploading

Convert PDFs to JPG, PNG, plain text and Markdown, turn images into PDFs, run OCR on scanned pages, chat with a document using AI, compress for email, and compare versions. All in the browser.

Most documents do not arrive in the format you need them in. A scanned contract is a stack of images that you need to read as text. A product catalogue arrives as a PDF and the design team needs JPGs of every page for the social rollout. A long legal brief is easier to summarize when you can ask a question in plain English. A report grew too large to email and you need a smaller copy that still reads cleanly. The convert toolkit is the bridge between PDF and the formats next to it. This page collects every PdfWiseAI tool that changes a document's format rather than its internal structure: turning PDF pages into images, turning images into a PDF, pulling readable text out of a PDF, running OCR on image-only scans, asking a question about a document using AI, shrinking a PDF for delivery, and comparing two versions of a document side by side. Image export, text export and OCR all run locally in the browser. AI chat is the only operation that sends document text to a remote service, and only the text needed to answer the question — the binary PDF is not transmitted. If you know what format you need, jump to that section. If you are not sure whether a file is a real PDF or a scan of one, the OCR section explains how to tell the difference and what to do next.

PDF to Images

How to convert PDF pages to JPG or PNG

Export every page of a PDF as a high-quality image. Useful for presentations, design previews, social posts, thumbnails and any system that accepts images but not PDF documents. Choose JPG for small file size or PNG when you need pixel-exact rendering with no compression artefacts, then pick a quality level appropriate to the destination. Rendering runs locally, so the source PDF does not pass through a third-party conversion server.

Images to PDF

How to convert JPG and PNG images to PDF

Combine photos, scans, receipts or screenshots into a single PDF. Each image becomes one page, in the order you select, and the result is a PDF that is easier to share, archive and annotate than a folder of loose files. Useful for expense reports, scan bundles, portfolios and application documents. The PDF is created in the browser; the source images are not uploaded.

PDF to Text

How to extract text from a PDF

Pull the readable content of a PDF out as a plain text file, with page boundaries preserved so the output can be traced back to the source. Useful for notes, analysis, search and reuse. The tool works best with digitally generated PDFs that contain selectable text. Scanned, image-only documents need OCR first — see the OCR section below for that workflow.

OCR PDF

How to OCR a scanned PDF

Run optical character recognition on image-only PDFs in the browser. Tesseract.js renders each page at 2× resolution and detects the text, producing a page-by-page text report you can download. Useful for digitising paper records, making scanned documents searchable, and unlocking text that an image viewer cannot select. If a PDF already has selectable text, OCR is skipped automatically to save time.

Chat with PDF

How to chat with a PDF using AI

The only operation on this page that does not run entirely in the browser. PdfWiseAI reads the text out of the PDF locally, then sends the relevant text plus your question to an AI service. The binary PDF never leaves your device. Useful for summarising a long contract, extracting amounts and dates, comparing two clauses, or producing a structured table from a long document. Always verify the cited pages before relying on the answer.

Compress PDF

How to compress a PDF for sharing

Reduce the file size of a PDF before emailing it, sharing it through a chat app or uploading it to a portal. The compression tool offers several levels so you can balance file size against image quality — start with the recommended setting and step up to stronger compression only if needed. Runs locally, so the source PDF is not uploaded. Best results come from documents where images dominate the size; text-only PDFs are usually already small.

Compare PDFs

How to compare two PDF versions

When you have two versions of a document and need to know what changed, the compare tool renders each page of both PDFs and computes a pixel-level diff. The on-screen summary lists every page that differs and the percentage of change, and the downloadable report highlights the differences in red. Useful for reviewing redlines, spotting a bad save, or auditing changes between revisions.

06Is the chat tool different from the other tools on this page?: Yes. The other six operations on this page run entirely in your browser. The chat tool reads the text locally and sends the necessary text plus your question to an AI service. The binary PDF is not transmitted, but the extracted text of the relevant pages is. Review the AI provider's data policy if that matters for your document.
