Step 1: Upload your PDF. Open Sejda’s Compress PDF tool. Click Upload PDF file (or drag and drop). You can also pull files from Google Drive, Dropbox, OneDrive, or a web URL via the upload menu. Multiple files are supported when you need to shrink more than one PDF.

Step 2: Compress (or open More options). Click Compress for the default optimized result, then Download the smaller PDF. For finer control, open More options and adjust:

• Image quality: Medium (common default, around JPEG quality ~65%), Good, or Best — higher quality means a larger file.

• Image resolution (PPI): Standard optimization often targets about 72 PPI; raise to 144 / 288 / 720 (or similar available values) when print clarity matters more than size.

• Image conversion: choose Grayscale when color isn’t required and you want a smaller output.

• Multimedia / fonts: discard or keep multimedia; optionally optimize fonts when offered.

• Faster compression: skip tiny images and focus on larger ones to finish sooner on image-heavy files.

Step 3: Download and check. Open the compressed PDF and confirm text stays sharp enough for your use case (email, web share, or light print).
