When to use online PDF tools

Real use cases for PDF tools

Compress PDFs for email and upload

Reduce PDF file size for email attachments, form uploads or cloud storage — without losing text clarity or image quality.

Merge documents into one PDF

Combine reports, invoices, contracts or presentations into a single PDF. Reorder pages by dragging before downloading the merged result.

Split large PDFs into smaller files

Extract specific pages or split a large PDF into separate documents. Useful for sharing individual chapters, invoices or sections from a larger file.

Convert PDF pages to images

Export pages as high-resolution JPG or PNG images for presentations, thumbnails, social media or web display. Each page becomes a separate image file.

Convert images to PDF

Combine multiple JPG or PNG images into a single PDF document. Set page size, adjust image fit and download the result instantly.

Complete guide to working with PDF files online

Why PDF files become large — and how to fix it

PDF file size depends on what the document contains. Text-only PDFs are usually small — a 100-page contract may be under 1 MB. PDFs with embedded images are much larger — a scanned document or a PDF exported from a presentation can easily reach 50–200 MB. Embedded fonts add to file size, and PDFs from design applications often include high-resolution images far beyond what screen viewing requires. The most effective way to reduce PDF file size is compression: rasterizing pages to images at screen resolution removes excess image data and font embedding overhead. For email attachments, compress PDF to under 10 MB for reliable delivery across most email providers.

How to reduce PDF file size without losing quality

The best approach depends on the PDF type. For image-heavy PDFs — scanned documents, presentations, brochures — compression is the most effective option. Compressing at 80–85% quality reduces file size by 60–80% with no visible difference at screen resolution. For text-heavy PDFs — contracts, reports, legal documents — PDF compression may have limited effect since text is already compact. In this case, consider removing embedded fonts or unnecessary metadata. For shared documents that need to remain editable, avoid rasterizing as this converts all text to images and removes text searchability.

PDF vs JPG vs PNG — when to convert and when to keep the original

Keep PDF format when the document contains multiple pages, when text searchability matters, or when the file will be printed. Convert PDF to JPG when you need to share individual pages as images — for social media, website uploads or email previews. JPG is the best choice for PDF pages with photographs or complex graphics. Convert PDF to PNG when the page contains elements with transparency — logos, charts, or any content where a transparent background is needed. PNG preserves all detail losslessly, making it ideal for pages that will be further edited in design software.

Frequently asked questions

Yes. Every tool is free with no usage limits, no watermarks on output, and no credit card required.

No. All PDF processing runs entirely in your browser using PDF.js and pdf-lib. Your files are never sent to any server.

There is no server-side file size limit. PDFs up to 50 MB work well in modern browsers. Very large PDFs may take longer on older devices.

PDF Compressor rasterizes pages to images, which makes text non-searchable in the output. PDF Merge and Split preserve all original content including searchable text.

Yes. All tools are fully responsive and work on iOS Safari, Android Chrome, and all modern mobile browsers.

Use PDF Compressor and set quality to 80–85%. At this level, images in the PDF are re-encoded at high quality but significantly smaller size — 60–80% reduction for image-heavy PDFs with no visible difference on screen. Text content is preserved.

Use PDF Merger — upload multiple PDF files in any order, reorder pages if needed, and download the combined document. All merging runs in your browser with no upload.

Use PDF Splitter — upload your PDF, select the page range or pages you want to extract, and download the result as separate PDF files or as a ZIP archive.

These tools handle structural operations — compression, merging, splitting and conversion. Editing text inside a PDF requires a PDF editor, which is a different type of tool.

Use PDF to JPG — upload your PDF, each page is rendered and exported as a separate JPG image. Download individual pages or all pages as a ZIP archive.

Yes. All tools on Ceroxi process files entirely in your browser — nothing is uploaded to any server. Your PDFs stay on your device at all times. This makes them safe for confidential documents: contracts, medical records, financial statements and any file that should not touch a third-party server.

Yes. PDF Merge combines files by joining their internal page streams — no re-encoding or rasterization happens. Text stays searchable, images stay at their original resolution, and all internal links and bookmarks are preserved. The merged PDF is identical in quality to the originals.
