Compress PDF to 1MB or Less — Free, No Upload

Reduce a PDF to 1MB or below with an automatic target-size workflow. Tuko processes the file locally and tells you whether the 1MB target was reached.

Compress your PDF to under 1MB

Choose your PDF and Tuko tries progressively stronger settings until it fits. Free, no account, and nothing is uploaded.

A 1MB limit is much stricter than a normal email attachment limit. Tuko's target-size workflow removes the guesswork: add the file above, keep 1MB selected, and let the compressor try progressively stronger settings.

Before and after: what compression changes

How much a PDF shrinks depends on what is inside it. These are the three kinds of file people bring most often, and what to expect from each.

Phone photos saved as a PDF

Before: Each page is a full camera photo. A few pages can add up to several MB because the photos keep every pixel the camera took.
What Tuko does: Smart compression shrinks and re-encodes the photos inside the PDF. The page layout stays the same.
After: Usually the biggest drop. Zoom in on small print, IC numbers and signatures before you upload.

High-resolution scan from a scanner or copier

Before: Every page is one large image, often scanned at a higher resolution than any portal needs.
What Tuko does: If Smart compression is not enough, Tuko can redraw each page at a smaller size until the file fits.
After: The file gets much smaller, but text becomes part of the image and can no longer be selected or searched.

PDF exported from Word or a website

Before: Mostly text and vector graphics, with few or no photos. These files are usually small already.
What Tuko does: There are few images to shrink, so Smart compression changes very little.
After: If it is still too big, look for one large embedded image or remove pages you do not need.

Quick check: will it fit under 1MB?

Divide the limit by the number of pages. Under 1MB, a 5-page file has about 204 KB per page and a 10-page file about 102 KB per page. If that is far below what one page of your file uses now, remove pages you do not need or split the file before compressing.

Protect readability first

Start with Smart compression. If 1MB cannot be reached, stronger compression may flatten pages into images. Always zoom in on names, ID numbers, dates, signatures, and fine print before uploading the result.
