About this tool
Plenty of forms and portals reject files above 1 MB. This tool finds the highest quality that fits: it first optimizes the PDF structure without touching the content and, if that is not enough, renders the pages as images and tunes the quality until the file lands just under 1 MB.
You see the size before and after, prior to downloading. If your PDF is already under 1 MB, you get it back optimized, never degraded. Everything runs in your browser: the file is never uploaded.

Questions
- What if my PDF is already under 1 MB?
- Only the lossless optimization runs. We never return a file larger than the original or degrade a PDF that already fits.
- Will I lose quality compressing to 1 MB?
- It depends on the starting point. If pages have to be rendered as images, text stops being selectable and sharpness drops in a controlled way; the tool picks the highest quality that fits and tells you before you download.
- Why didn't it reach exactly 1 MB?
- Very long or image-heavy documents can have a readable minimum above the target. In that case you get the smallest file that is still readable, clearly flagged.
