WHO USES ZIPPY
Everyday document work, made easier.
Small, practical workflows for people who need to get a PDF ready and move on.
Office & project teams
Join reports, remove blank pages, reorder sections and prepare a clean handoff for colleagues or clients.
Small businesses
Organize invoices and scanned records, crop page edges and reduce oversized scans before sharing.
Researchers & educators
Split reading packs, keep selected chapters, rotate scans and export individual pages for teaching material.
QUICK WORKFLOWS
Six tools. Six straightforward ways to finish the job.
Each guide follows the same idea: choose a file, make the specific change, check the result, then save a new copy.
01 / MERGE PDFs
Build one document in the right order.
Start with the main document, then add supporting files in the order someone should read them. Check the page counts and file names before merging.
A clean merge
- Add all PDFs at once or use Add PDFs.
- Move each file into its final reading order.
- Check the list, then select Merge PDFs.
02 / SPLIT
Keep only the pages you need.
Use a page range when you need a specific section, odd/even rules for duplex workflows, or fixed-size groups when a large document needs to be divided.
Keep selected content
- Choose the split rule that matches the job.
- Enter page numbers such as 2-5, 8, 11-14.
- Review the output count and download the files.
03 / CROP & ROTATE
Trim margins without losing your place.
Work on one large page preview at a time. Use the thumbnail strip to move through the document, draw the crop area inside the page, and review the cropped preview before saving.
A precise crop
- Open the page you want from the thumbnail strip.
- Drag a rectangle around the area to keep.
- Use Revert crop to undo, or apply matching margins to all pages.
Cropping hides page areas; it is not secure redaction.
04 / REARRANGE
Make the page order feel natural.
Use the visual page board when the PDF is already combined but the sections are out of sequence. Drag thumbnails directly into position and remove pages you do not need.
A clean page flow
- Scan the thumbnails to understand the current order.
- Drag a page onto its new position.
- Restore removed pages if needed, then save the new PDF.
05 / COMPRESS
Choose a DPI that suits the document.
Zippy estimates the effective DPI of embedded raster images before export. Choose a lower target only when it meaningfully reduces resolution; the final file is compared with the original before a download is offered.
Pick the right output
- Review the detected source DPI and suggestion.
- Choose 72 or 96 DPI for smaller sharing copies, 150 for everyday reading, or 300 for print detail.
- Keep the result only when it is genuinely smaller.
Raster compression flattens text, links and vectors into images.
06 / PDF TO PNG
Export only the pages you want to reuse.
Render a single page for a slide or a selected range for a document preview. Higher output scales preserve more detail but use more memory and create larger images.
Export page images
- Enter page numbers or ranges.
- Choose a render scale that suits the destination.
- Render and download the generated PNG files.
BUILT AROUND THE TASK
Practical tools. Clear outcomes.
No maze of settings. Each operation has a simple path from choosing files to downloading the result.
See your file order
Review the selected documents before merging. Move files up or down, remove mistakes, and export only when the list looks right.
Make precise changes
Extract page ranges, rotate pages, remove unwanted pages, and reorder a document without changing your source file.
Compression with context
Image-based compression can shrink scanned files, but it rasterizes text and vector content. Zippy explains that trade-off before export.
EVERYDAY PDF WORK
A browser-based PDF workspace for common document tasks.
Merge, split and organize PDF files
Combine multiple PDFs into one ordered document, extract selected page ranges, or reorganize an existing document by moving, rotating and removing pages. Zippy creates a new output file so your original stays unchanged.
Crop, rotate and export PDF pages
Crop page edges with a visual selection, rotate individual pages, or use the thumbnail organizer to change order and remove pages. Export selected pages as PNG images when you need page artwork outside the PDF. Raster compression can help with scanned or image-heavy documents, with a clear trade-off: text and vector content become images.
FAQ
Common questions.
Are my files uploaded to a server?
No. Document operations run in the active browser tab. The PDF.js and pdf-lib libraries load from cdnjs when you first select a file, but your PDF content is processed locally.
Does Zippy change my original PDF?
No. Zippy reads the selected file and creates a separate result. Your original file stays where it is on your device.
How do I merge PDFs in the right order?
Add the files, arrange them from first page to last section, check the file names and page counts, then merge. The new PDF follows the order shown in the list.
How does Split work?
Extract custom page ranges, keep odd or even pages, create one PDF per page, or split the document into groups of a chosen page count.
Can I crop only one page?
Yes. Select a page, draw the area to keep and save. You can also apply the same crop to all pages when the pages share matching margins.
Is crop the same as redaction?
No. Crop changes the visible page area but does not securely erase hidden content outside that area. Do not use it to conceal confidential information.
Can I rotate a single page?
Yes. Choose the page in Crop & Rotate and use the rotation controls. Other pages keep their current orientation unless you apply the adjustment to all pages.
How do I rearrange pages?
Open Rearrange, drag page thumbnails into the desired order, remove pages you do not need, and save a new PDF.
How does PDF compression work?
Zippy estimates the effective resolution of embedded images, then renders each page to JPEG at your selected target DPI and rebuilds the PDF. This is a lossy, page-rasterizing method: selectable text, links, vector artwork, forms and accessibility structure are not retained.
How does Zippy detect the original DPI?
It samples pages, reads embedded image dimensions and their displayed size on the PDF page, then estimates the effective DPI. Vector text and drawings do not have a single source DPI, so they are reported separately.
Which compression DPI should I choose?
72 DPI is for very small sharing copies, 96 DPI for general screens, 150 DPI for everyday document reading, and 300 DPI when retaining more print detail matters. The best choice depends on the source images and the text size.
What if the compressed PDF is larger?
Zippy compares the generated file with the original and requires at least 1 KB and 1% savings before offering a compressed download. A larger file or a negligible saving is rejected, so you can keep the original or try a lower DPI.
What if a PDF is already low-resolution or mostly vector?
There may be little to gain from raster compression. Zippy reports when no meaningful source image DPI can be measured, and the final size check prevents a larger result from being presented as a saving.
Can I export PDF pages as PNG?
Yes. Choose individual pages or ranges, select a render scale and export each selected page as a separate PNG image.
What if a PDF is password-protected or damaged?
Zippy reports protected or unreadable files before the affected operation continues. It does not attempt to bypass password protection.
Can I use Zippy on mobile?
Yes. The workspace adapts to touch screens, including the crop page navigator and the page organizer. Very large or complex PDFs may still be limited by the device's available memory.
