PDF 压缩清单

在压缩 PDF 之前和之后，这些都是值得检查的东西——完全基于 PDFPilot 的压缩 PDF 工具的工作原理，而不是一般的建议。

• Confirm whether you need the compressed file's text to stay selectable/searchable — compression re-encodes every page as an image, so if searchable text matters, keep the original alongside the compressed copy.
• Choose a quality level intentionally: Maximum Compression for the smallest file, High Quality when visual fidelity matters more than size. Open Compress PDF
• After compressing, check the page count matches the original — compression changes file size and image quality, never page count or order.
• Open the compressed file and spot-check a photo-heavy page at actual size before sending it anywhere — this is the fastest way to catch a quality level that was too aggressive.
• If the file is still too large after Maximum Compression, the content itself may need splitting rather than further compression. Open Split PDF
