Turn screenshots into a readable document by controlling order, crop, page size and text legibility.

Learn why lossless PNG images can create large PDFs, especially when photographs or oversized screenshots are embedded at full resolution.

Use pixel size, intended DPI and PDF page geometry to predict how large an image will appear on a PDF page.

Understand why PNG can stop additional lossy saves but cannot reconstruct detail already discarded by JPEG compression.

Use PNG as an intermediate when repeated JPEG re-encoding would add more loss, while understanding what the conversion cannot fix.

Understand ICC profiles, sRGB interpretation and gamma when the PNG looks lighter, darker or differently saturated than the JPG.

Compare lossy JPEG and lossless PNG behavior to understand why a simple format change can increase file size dramatically.

Choose the intended background before PNG transparency is flattened into a JPEG that has no equivalent alpha channel.

Use JPEG for photo-like PNG content when a smaller file matters, while validating visible compression artifacts.

Protect sharp edges and small UI text by understanding how JPEG compression behaves around high-contrast graphics.

Balance file size against visible artifacts using the actual viewing size and content type instead of treating one quality number as universal.

Compress the parts that actually consume bytes—especially images—while protecting readable text, diagrams and the source file.

Work backward from the portal limit, compress with margin, and validate both file size and readability before uploading.

Diagnose scan resolution, color mode and page-image dimensions before compressing a scan blindly.

Use a target-size workflow for limits such as 500 KB, 1 MB or 2 MB instead of repeatedly trying random compression settings.

Create a smaller shareable PDF from selected pages while checking that sensitive or irrelevant pages are not included.

Handle portals that limit the number of pages by creating logical page ranges instead of compressing a file that is already small.

Map document structure to page ranges so each exported PDF represents a complete section instead of an arbitrary slice.

Distinguish the PDF page index from printed page numbers so covers, Roman numerals and inserted pages do not shift your selection.

Use page images when a destination accepts images or needs a preview, while understanding what is lost compared with the original PDF.

Calculate useful pixel dimensions from PDF page geometry and the intended display or print size instead of exporting blindly.

Diagnose low render resolution, later resampling and antialiasing instead of assuming the PDF text itself was blurry.

Choose the correct workflow by distinguishing original image objects from a rasterized picture of the entire PDF page.

Shrink the file without turning a sharp, searchable resume into a blurry scan.

Protect small type, thin rules and clickable text while reducing bytes.

Treat the scan as an image problem first, then verify that names, dates and fine text still survive.

Choose between compression and link sharing based on the real message limit and the recipient workflow.

Reduce image-heavy pages first and validate the exact file the recipient will open.

Understand why page images grow quickly and which scan choices matter before compression.

Build a PDF that keeps the page image while adding machine-readable text for search and selection.
