Usage Instructions

Compress PDF files in your browser

Use this tool when a website, email, or form requires a smaller PDF—for example under 2 MB, 5 MB, or 10 MB. Choose quality (Recommended / Maximum) or target size, and batch compress several files. Your files stay on your device; nothing is uploaded.

Common uses

Upload limits on government or school portals
Email attachment size limits
Sharing scans or contracts over chat apps
Shrinking scanned documents before archiving

Steps

Add files — Drag PDFs here or click to select (up to 10 files, up to 100 MB each). They appear in the queue as Waiting.
Choose how to compress
By quality — *Recommended* balances size and clarity (~150 DPI); *Maximum* aims for the smallest file (~96 DPI, lower clarity).
By target size — Pick 2 MB, 5 MB, 10 MB, or enter a custom size (1–100 MB). The tool will try to meet it; see the note on each file if the target could not be reached.
Remove metadata (optional) — Compression builds a new PDF and does not keep original file properties. When enabled, tool identification fields are omitted when possible. Does not change visible page content.
Compress — Click Compress. Files are handled one at a time. Preview the first page and compare sizes when done.
Download — Download a single file, or Download All as a ZIP (when total output is within the ZIP limit).

Tips

Situation	Suggestion
Scanned or photo PDF	Start with Recommended; use Maximum if you need a smaller file
Must be under a size limit	Use target size mode and check the result message on each file
Mostly text or vector PDF	Size may stay the same or increase; original is kept—do not use if you need selectable text
Several files	Add up to 10; they process in order

Before you compress sensitive files

Processing is local, but anyone with access to your device or screen can see the file. Close the tab when finished, or clear the queue with Clear. For highly sensitive documents, use a trusted device and a private network.

FAQ

Q: How do I compress a PDF?: A: Drag PDF files into the upload area, or click to select them. Choose how to compress: by quality (Recommended or Maximum) or by target file size (2 MB, 5 MB, 10 MB, or a custom size). Turn on Remove metadata if you want output without tool identification fields. Click Compress. When each file is done, check the original size, new size, and savings. Download one file or use Download All for a ZIP.
Q: What does this tool compress?: A: Each page is rendered as a compressed image and assembled into a new PDF—it does not simply re-compress existing image streams inside the file. Scanned documents and photo-heavy PDFs usually shrink the most. PDFs that are mostly text or vector graphics may change little or even grow after rasterization; in that case the original file is kept. Text is generally no longer selectable or searchable (similar to a scan). The output is still a PDF.
Q: Can I still select or copy text after compression?: A: Usually not. This tool reduces size by turning each page into an image, so the result behaves like a scanned PDF. If you need selectable, editable text, do not use this tool.
Q: Will target file size always be met?: A: The tool tries to reach your target (for example under 2 MB), but it cannot guarantee it for every file. If the target cannot be reached, you will see a notice and get the smallest result the tool could produce. If compression would not make the file smaller, the original file is kept.
Q: What does Remove metadata do?: A: Compression creates a brand-new PDF; it does not copy author, title, or creation date from the original. When Remove metadata is off, the output may include tool identification fields; when on, those fields are omitted when possible. Visible page content is unchanged either way.
Q: Are my PDFs uploaded to a server?: A: No. Compression runs in your browser on your device. Your files are not sent to ToolGee or any other server.
Q: What are the file limits?: A: Up to 10 PDFs at once. Each file can be up to 100 MB. Files are processed one at a time. Download All packs results into a ZIP when the total output is 500 MB or less; if the total is larger, download files individually.
Q: Why did compression fail or the page become slow?: A: Common reasons: the file is very large or has many pages, the browser is low on memory, or the PDF is protected or damaged. Compression renders each page in the browser, so large files may briefly slow the page; a warning also appears when the queue total is around 300 MB or more. Close other tabs and try again, use a desktop browser for large files, or compress fewer files at a time. Password-protected PDFs must be unlocked before use.
