4Easysoft PDF Converter Platinum: Best Settings for Quality and SizeConverting PDFs while balancing image/text quality and resulting file size is a common challenge. 4Easysoft PDF Converter Platinum offers a wide range of options to optimize output for different needs—print-ready documents, web distribution, email attachments, or archival storage. This guide walks through the best settings and workflows to get the highest possible quality when you need it and the smallest possible files when size matters, plus practical tips for mixed goals.
Overview: What affects PDF quality and size
Several PDF elements influence final file size and perceived quality:
- Images (resolution, color depth, compression)
- Fonts (embedded vs. referenced, subsets)
- Vector graphics vs. rasterized content
- Embedded objects (multimedia, forms, annotations)
- PDF version and compatibility settings
- Metadata and unused objects
4Easysoft PDF Converter Platinum exposes controls for many of these elements—image compression and DPI, font embedding, output format options (PDF/A, optimized PDF), and page range selection—so you can tailor results precisely.
Best settings when quality is the top priority
Use these settings when preparing documents for printing, professional distribution, or archiving where fidelity is critical.
- Output format and compatibility
- Choose PDF (Standard/High Quality) or PDF/A if long-term archiving is required. PDF/A ensures self-contained files with fonts and color info embedded.
- Set compatibility to a recent PDF version (e.g., PDF 1.⁄1.7) to allow modern compression and color profiles.
- Image handling
- Set image downsampling to none or a very high DPI (300–600 DPI) for print.
- Use lossless compression (ZIP) or maximum quality JPEG if file size is secondary.
- Preserve original color profiles (sRGB, Adobe RGB) for accurate color.
- Fonts
- Enable Embed all fonts or at least Embed subset fonts to maintain layout and typography.
- Avoid font substitution by checking for missing fonts before conversion.
- Vector content and text
- Keep vectors and text as vector objects—do not rasterize—so they remain sharp at any zoom level.
- Ensure OCR (if used) retains the original image and adds a hidden text layer rather than replacing the image.
- PDF settings
- Disable any automatic optimization or aggressive compression options.
- Include metadata for archiving (title, author, creation date) as needed.
Result: Larger files but maximum fidelity for print and professional use.
Best settings when file size is the top priority
Use these settings for quick sharing, web uploads, email attachments, or mobile viewing.
- Output format and compatibility
- Choose Optimized PDF or set compatibility to PDF 1.4 to use widely supported compression.
- If distribution target supports it, consider reduced-quality PDF presets.
- Image handling
- Downsample images to 96–150 DPI for screen-only viewing.
- Use JPEG compression with a quality setting around 50–70%—this gives good visual quality with substantial size savings.
- Convert color images to sRGB and where acceptable, convert to grayscale for purely text documents.
- Fonts
- Use subset embedding rather than embedding full fonts.
- If possible, replace uncommon fonts with common system fonts prior to conversion to avoid embedding large font files.
- Remove unnecessary elements
- Strip metadata, unused objects, hidden layers, annotations, and form data if not needed.
- Flatten layers and remove bookmarks/attachments that bloat file size.
- Linearization (web optimization)
- Enable fast web view (linearize) so the PDF can be loaded progressively when hosted online—this doesn’t shrink file size much but improves perceived load performance.
Result: Much smaller files suitable for sharing, with acceptable visual quality for screens.
Balanced settings for mixed goals (quality + size)
When you need a compromise—good-looking documents that remain reasonably sized—use these middle-ground settings:
- Image downsampling: 150–200 DPI
- Image compression: JPEG at 70–85%
- Fonts: Subset embedding
- Keep vectors and text as vectors; avoid rasterizing unless necessary
- Strip unnecessary metadata and attachments
- Use an optimized PDF preset that targets “web & print” or “balanced” quality
This typically reduces file size substantially compared to print-quality settings while keeping documents crisp in both print and digital viewing.
Practical workflows and tips in 4Easysoft PDF Converter Platinum
- Batch processing
- When converting multiple files, set a consistent preset. Create two presets—“High Quality (Print)” and “Small Size (Web)”—to switch quickly depending on the target.
- Page ranges and extraction
- Convert only necessary pages. Splitting large PDFs into sections removes unused content and reduces size.
- Use OCR selectively
- OCR is helpful for making scanned PDFs searchable, but full OCR + image preservation increases size. For size-sensitive tasks, use OCR-only with lower image DPI or apply OCR and then discard high-resolution images.
- Pre-process source files
- For Word or PowerPoint sources, compress or downsample embedded images before exporting to PDF.
- Replace high-resolution background images with optimized versions for presentation or web PDFs.
- Preview and iterate
- Convert a representative sample page with chosen settings, compare file size and visual quality, then adjust DPI or JPEG quality in small steps until the balance is right.
Quick recommended presets
- Print/Archive: PDF/A or PDF 1.7, No downsampling, Lossless compression, Embed all fonts.
- Web/Email: PDF 1.4, Downsample to 96–150 DPI, JPEG quality 60–70%, Subset fonts, Strip metadata.
- Balanced: PDF 1.5–1.6, Downsample to 150–200 DPI, JPEG quality 75–85%, Subset fonts, Optimize/linearize.
Troubleshooting common problems
- Blurry text after conversion: Check that text wasn’t rasterized—keep text as live text or increase downsampling DPI.
- Missing fonts: Enable embedding or install/match system fonts prior to conversion.
- Large files despite optimizations: Look for embedded multimedia, attachments, or full embedded fonts—remove or subset them.
- Poor color: Ensure color profiles are preserved and convert everything to sRGB for consistent screen color.
Final notes
Test settings on representative pages and create presets in 4Easysoft PDF Converter Platinum to save time. Choose aggressive quality settings for print and conservative ones for sharing; the right balance depends on target device and audience.
