Will the JPG be sharp?

Sharpness scales with DPI. 150 looks crisp on standard screens; 200+ holds up when printed; 72 is fine for thumbnails. Raise the JPEG quality slider toward 95 to keep edges clean.

Can I export only specific pages?

Not directly — every page is converted. Use the Split tool first to extract just the pages you want, then convert the smaller PDF to JPG.

What's the difference between PDF to JPG and PDF to PNG?

JPG is lossy and smaller; PNG is lossless and bigger. Pick JPG for photographic scans, PNG for sharp text, screenshots and line art where compression artefacts would show.

Is this PDF toolkit free?

Yes. folio is free to use, no account is required, and there are no paid plans.

Are my PDFs uploaded to a server?

No. folio runs entirely in your browser. Your PDFs are never uploaded, never seen by our infrastructure, and never stored anywhere outside your device. When you close the tab, every file is gone.

Which operations are supported?

Merge PDFs, split a PDF into ranges, compress a PDF, convert PDF pages to JPG or PNG, build a PDF from images, rotate all or selected pages, add a watermark, and extract plain text. All of this happens in your browser.

Is there a file size limit?

Yes. Each file may be up to 100 MB. Browser memory is the real ceiling — very large scanned PDFs may struggle on lower-end devices.

Can I work with multiple PDFs at once?

Yes. Merge and Images→PDF accept up to 20 files in a single batch. Split, Compress, Rotate, Watermark and Extract Text take one PDF at a time.

Will my converted images / PDFs lose quality?

Compress and PDF→JPG/PNG re-render pages at the DPI/quality you pick, so there is a small generational loss like any image re-encode. Merge, Split, Rotate, Watermark and Extract Text do not re-render — they only edit the existing PDF objects, so quality is preserved.

Can folio open password-protected PDFs?

Not yet. If your PDF requires a password to open, please unlock it first in a dedicated app. We deliberately skip password handling to keep folio fully client-side and free of legal grey areas.

Not in this version. Extract Text only works for PDFs that already have selectable text. Scanned image-only PDFs need OCR, which is a separate, much heavier project we may add later.

Why does the first PDF→Image take a moment?

When you first use an operation that renders PDF pages (PDF→JPG, PDF→PNG, or split previews), folio downloads the rendering engine (~1 MB). After that it stays cached and subsequent operations start immediately.

Are ads required to use the tool?

No. Ads are isolated from the converter. The tool works completely even if ads fail to load or are blocked.

About PDF to JPG

When should I choose JPG?

JPG is smaller than PNG but uses lossy compression — perfect for photographic scans, screenshots and content where slight softness is acceptable. For sharp text or screenshots with hard edges, choose PDF→PNG instead.

What DPI should I use?

150 DPI is the sweet spot for screen viewing. Push to 200–300 if you'll print the result. 72 DPI is fine for thumbnails and saves bandwidth.

Multiple pages = a ZIP

If your PDF has more than one page, folio bundles all the JPGs into a single ZIP so you get one download. A one-page PDF returns a single JPG directly.

About this operation

PDF → JPG

What it does

folio uses pdf.js to render every page of your PDF onto a canvas and writes the result as a JPG. You control the DPI (50–200, default 150 for screen viewing) and JPEG quality (30–95). Multi-page PDFs come back as a single ZIP; one-page PDFs come back as a bare JPG. JPG is the right choice for photographic scans, complex screenshots and any content where small file size matters more than razor-sharp edges.

When to use it

Email a single PDF page as an inline image
Generate thumbnails of every page for a gallery
Pull a chart or diagram out of a longer PDF
Prep slides for embedding in chat or docs

Limitations — what it doesn't do

Lossy compression — sharp text and line art may show JPG artefacts
No way to pick specific pages — every page is rendered (use Split first)
Cannot decode password-protected PDFs
Multi-page output always comes back as a ZIP, not loose files

Every tool runs entirely in your browser.

Frequently asked questions

Your PDFs never leave your device

folio is a static page. Every operation runs inside your browser via pdf-lib (edit) and pdfjs (render). There is no server-side processing, no upload, no temporary file, no cache. When you close this tab, every file is gone.
