Shrink a PDF's file size by recompressing its embedded images, while keeping text sharp and selectable.
Low keeps the most detail; High gives the smallest file size. Text and vector content are never altered at any level.
Large PDFs are often large because of the photos or scans inside them, not the text. PDF Compress finds the embedded images in your document, recompresses them at your chosen level, and rebuilds the file — leaving every word of text exactly as sharp and selectable as it started.
Drop in a PDF, check the preview and original size, choose a compression level, then tap Compress PDF. Review the size comparison, and download if it's smaller — if it isn't, the tool tells you honestly rather than replacing your file with a bigger one.
Will this make my text blurry?
No — only embedded images are recompressed. Text, fonts, and vector graphics are left completely untouched, so they stay sharp and selectable.
What if my PDF doesn't get any smaller?
Some PDFs are already efficiently compressed, or contain mostly text with few images. In that case, the tool tells you directly and keeps your original file rather than replacing it with something larger.
Which images does this compress?
Images embedded using JPEG compression, which covers the large majority of photos and scans in real-world PDFs. Images using other internal formats are left unchanged to avoid any risk of visual corruption.
