About ReduceMyFileSize

ReduceMyFileSize is a collection of free online tools for making files smaller and converting them between common formats — no sign-up, no software to install.

What you can do here

• Images — compress JPG, PNG, WebP, AVIF, GIF, BMP, TIFF and HEIC, resize them, and convert between formats.
• PDF — compress PDFs and turn images into a PDF.
• Documents — shrink Word, Excel and PowerPoint files, and convert Office documents to PDF.
• Video & audio — compress and convert common video and audio formats.
• Base64 — encode any file to a Base64 text string, or decode it back.

The exact tools available depend on the software installed on the server you are using; tools that cannot run are hidden automatically.

How it works

You choose a file (or several), optionally set a target size or quality, and the file is processed on our server. When it's done, you download the result. Image and Base64 tools run entirely in PHP; the PDF, Office, video and audio tools use trusted open-source programs such as Ghostscript, LibreOffice and FFmpeg where they are installed.

A requested target size is treated as a goal, not a guarantee — we get as close as the format allows while keeping the file usable.

Privacy in short

Your uploaded file is used only to produce your result. The raw upload is removed from the server immediately after processing, and generated results are cleaned up automatically afterwards. For the full details, see our Privacy Policy.
