PDF tool
Simple 3-step flow
One file at a time. Pick Safe for structure, or Lossy when a scan has to shrink.
01
Drop one file. It is read into this tab only.
Never leaves this device
02
Safe rewrites structure and keeps selectable text. Lossy flattens pages to JPEG.
Mode is in the tool, not a guess
03
When it finishes, the tool shows before/after size so you can see what actually changed.
No cloud copy retained
Optimization modes
Safe keeps selectable text. Lossy flattens scans to JPEG.
Rewrites with object streams. Drops orphaned objects. Image bytes stay as they are, so scan-heavy files often barely shrink. Text stays selectable.
Default when you need searchable text
Rasterizes each page to JPEG and rebuilds the PDF. Scans can shrink a lot. You lose search and copy.
Quality and scale sliders in the tool
Privacy architecture
Traditional web converters upload tax returns, contracts, and medical PDFs to a remote server. Fileraz never takes the file — Safe or Lossy both run in this browser tab.
Legacy cloud tools
Uploads the full document to a remote queue.
Fileraz
0 bytes leave this machine. pdf-lib runs in this tab.
Legacy cloud tools
Held on a server, then deleted on a timer.
Fileraz
Gone when you close the tab. No file server, no retention window.
Legacy cloud tools
Paywalls and daily caps on free tiers.
Fileraz
No daily cap. One PDF at a time — the ceiling is your RAM.
Honest output
Safe does not touch embedded images. Lossy turns pages into pictures. The workspace reports file size when processing finishes — we do not invent a 71% saving.
Answers
Why Safe barely shrinks scans, and what Lossy costs you.
Most large PDFs are large because of images inside them. Safe mode does not recompress those bytes — try Lossy mode if you accept flattened pages.
No. Each page becomes a JPEG image inside a new PDF. Use Safe mode when you need identical, searchable text.
Use Lossy mode here, rescan at lower DPI, or rebuild from compressed images. Ghostscript is the better option if you do this often.
Constraints
Safe mode does not recompress embedded images.
Lossy mode flattens pages — not suitable for accessible text PDFs.
One PDF at a time; before/after size shown after processing.
