The file never leaves your computer. No signup, no upload, no tracking.<\/p>\n<p>This tool shrinks PDF file size by choosing the safest compression path for each document. Text pages stay as PDF pages. Scanned and image-only pages can be re-rendered at lower image quality for stronger compression. Use the quality slider to control the scan\/photo tradeoff.<\/p>\n<h2>How it works<\/h2>\n<p>Most large PDFs are large because they contain high-resolution images (scanned pages, embedded photos, full-page graphics). This compressor checks each page for selectable text. Text pages are preserved. Image-only pages can be rendered in your browser and re-encoded at a lower quality setting.<\/p>\n<p>For PDFs that are already small or contain mostly vector text, compression will have limited effect because the tool prioritizes preserving the document over forcing a smaller but degraded output.<\/p>\n<h2>Common questions<\/h2>\n<p><strong>Will the text still be searchable after compression?<\/strong> Yes, when the input page has selectable text. The tool preserves text pages. Page flattening is reserved for image-only pages, such as scans without an OCR text layer.<\/p>\n<p><strong>How much smaller will my PDF get?<\/strong> Scanned documents (where every page is an image) often shrink a lot. PDFs with a mix of text and images shrink less. PDFs that are mostly text may not shrink at all.<\/p>\n<p><strong>Is there a size limit?<\/strong> No hard limit, but very large PDFs (50+ MB) will take longer to process since each page is rendered and re-encoded in the browser.<\/p>\n<nav class=\"df-related\" aria-label=\"Related tools\">\n<h2>Related tools<\/h2>\n<ul>\n<li><a href=\"\/merge-pdf\/\">Merge PDF<\/a><\/li>\n<li><a href=\"\/split-pdf\/\">Split PDF<\/a><\/li>\n<li><a href=\"\/pdf-to-word\/\">PDF to Word<\/a><\/li>\n<li><a href=\"\/pdf-to-text\/\">PDF to Text<\/a><\/li>\n<li><a href=\"\/word-to-pdf\/\">Word to PDF<\/a><\/li>\n<li><a href=\"\/pdf-to-jpg\/\">PDF to JPG<\/a><\/li>\n<\/ul>\n<\/nav>\n","protected":false},"excerpt":{"rendered":"<p>Need to shrink a PDF for an email attachment or an upload portal with a size limit?
