editpdf123 — Frequently Asked Questions

Everything about formats, quality, privacy and how Edit PDF 123 works.

General

Frequently asked questions

Is editpdf123.com free?
Yes — every tool is free, with no watermark and no account.
Do you keep my documents?
Files are processed in isolation and deleted shortly after download.
Will quality be preserved?
Merging, splitting and rotating preserve content exactly; compression removes only redundant data.

Merge PDF

Frequently asked questions

Can I control the page order?
Yes — files are merged in the order you upload them, so arrange them accordingly.
Does merging reduce quality?
No — page content is copied exactly, with no re-compression of text or images.
Is there a file limit?
There's a generous upload size cap; typical multi-file merges are well within it.
Is it free?
Yes — free, no watermark, no signup.

Split PDF

Frequently asked questions

How are the split pages delivered?
Each page of your document becomes its own single-page PDF, and all of those files are bundled into one ZIP archive. You download the ZIP once and then keep whichever pages you need.
Can I split out just a range of pages?
The tool splits the whole document into one PDF per page. To end up with a specific range, download the ZIP, keep the pages you want, and recombine them with the merge tool into a single file.
Does splitting reduce the quality of each page?
No. Page content is copied exactly with no re-compression, so text stays selectable and images stay sharp. An extracted page is a faithful copy of the original.
Can I put the pages back together later?
Yes. Use the merge tool to reassemble selected pages into one document, in whatever order you choose. Splitting then merging is a common way to rebuild a trimmed-down PDF.

Rotate PDF

Frequently asked questions

How many degrees does each pass rotate?
Each pass turns the document 90 degrees clockwise. Run it twice for a 180 degree fix on upside-down pages, or three times to reach 270 degrees.
Is the rotation saved permanently?
Yes. The new orientation is written directly into the PDF, so the page displays correctly in every viewer, on phones, and when printed, not just in the program you happened to use.
Will rotating reduce quality?
No. Rotation changes only the orientation flag. Text stays selectable and images keep their resolution, with no re-rendering or re-compression, so the file is as crisp afterward as it was before.
Can I rotate only one page instead of all of them?
The tool rotates every page in the document together. If only one page is sideways, a quick workaround is to split the PDF, rotate the affected page, then merge the pages back into one file.

Compress PDF

Frequently asked questions

How much smaller will my PDF get?
It depends on what is inside. PDFs with redundant data, duplicated fonts, or embedded images shrink the most, sometimes dramatically. A lean text-only document is already close to its minimum size and will change very little.
Will the document still be readable after compression?
Yes. The text and structure are preserved, so the document stays fully readable and its text stays selectable. Compression removes redundant data and inefficiencies rather than discarding the content itself.
Does compressing change the page count or order?
No. Compression works within the existing document, so the page count, order, and layout all stay exactly as they were. Only the file's internal data is streamlined.
Why did compression barely help my scanned PDF?
If a scan was already saved at a modest resolution there is little excess to remove. For very heavy scans, converting the pages to images and rebuilding a fresh PDF from them can sometimes save more than re-compression alone.

PDF to JPG

Frequently asked questions

What resolution are the JPGs?
Each page renders at 150 DPI, which keeps text sharp on screens and looks clean for light printing while keeping file sizes manageable. At that density a typical A4 page becomes a comfortably detailed image.
How are multi-page PDFs handled?
Every page becomes its own numbered JPG, and the full set is bundled into a single ZIP archive so you can download all of them in one click rather than saving each page separately.
Why convert to JPG instead of keeping the PDF?
Many platforms accept only images, not documents. Job boards, marketplaces, social networks, and chat apps often reject PDFs, so a per-page JPG lets you upload, preview, or paste content that would otherwise stay locked in the file.
Can I turn the images back into a PDF afterward?
Yes. The JPG to PDF tool rebuilds a document from images, placing each one on its own page in upload order, so you can edit pages as pictures and then reassemble them into a single PDF.

JPG to PDF

Frequently asked questions

Can I combine several images into one PDF?
Yes, that is exactly what this tool does. Add as many JPG or PNG files as you like and each becomes a page in a single PDF, arranged in the order you upload them.
Will my images lose quality in the PDF?
Photos are embedded at quality 90, so there is no visible loss for normal viewing or printing. The PDF acts as a container around your images rather than aggressively re-compressing them.
Does it accept PNG and transparent images?
Yes. PNG inputs work alongside JPG, and any transparency is flattened onto a white page so the document prints cleanly without unexpected dark or checkered backgrounds.
How do I control which image comes first?
Pages follow upload order, so name your files to sort correctly or add them one at a time in the sequence you want. Rotating sideways images in your gallery before uploading also avoids surprises.
