Can I rotate to an arbitrary angle?

No — PDF supports only cardinal rotations (90°, 180°, 270°). Arbitrary angles would require re-rendering each page as an image, which folio's PDF→JPG/PNG flow does.

Will rotating change file size or quality?

Barely. folio writes a rotation flag in the page metadata via pdf-lib's `setRotation`. Content is not re-rendered, so there's no quality loss and the file size only changes by a few bytes.

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.

Rotate PDF pages

Q: Can I rotate a single page or just some pages?

Yes — use the page filter input and type pages like `1, 3, 5-7` to target specific pages. Leave it blank or pick `All pages` to rotate the whole document.

Scanned the document sideways? Drop your PDF below, pick an angle, and folio rotates it inside your browser. Optionally limit the rotation to specific pages.

About Rotate PDF

Does rotating change the page content?

No. folio simply flips the rotation metadata on each page — pdf-lib's `setRotation` — so PDF viewers display the page at the new angle. Nothing is re-rendered, no quality is lost, and the file size barely changes.

How do I rotate only some pages?

Use the page filter and type pages like `1, 3, 5-7` to target specific pages. Leave it blank or pick `All pages` to rotate the whole document at once.

Can I rotate by any angle?

PDF only supports cardinal rotations: 90°, 180° or 270°. Free-angle rotations would require re-rendering the page, which is what folio's PDF→Image flow is for.

About this operation

PDF → PDF

What it does

folio flips the rotation metadata on each page using pdf-lib's `setRotation`. PDF viewers display the page at the new angle without re-rendering anything, so there's no quality loss and the file size barely changes. Type a page filter (`1, 3, 5-7`) to target specific pages or rotate the entire document at once. Only the three cardinal rotations are supported — PDF itself has no concept of an arbitrary-angle rotation in metadata.

When to use it

Fix a sideways-scanned page in a long PDF
Flip pages that came in upside-down from a phone scanner
Rotate a mixed-orientation report so every page reads the right way up

Limitations — what it doesn't do

Only 90°, 180° and 270° — no arbitrary angle (would require re-rendering)
Metadata-only change — content is not re-rendered, no transformation happens
Cannot rotate password-protected PDFs
Page filter syntax must be valid (`1, 3, 5-7`)

Every tool runs entirely in your browser.
