How do I make a PDF smaller and know the size?

Run Light, Balanced, or Maximum, then look at the download. Light repacks with object streams and keeps the original if the packed file is the same size or heavier. Balanced redraws at quality 0.72, and Maximum redraws at quality 0.55. Keep the preset whose file is light enough and still readable.

Which preset should I try first?

Start with Light. It is the gentle repack, and you keep the lighter of the packed file and the original. If the download is still above the size you need, try Balanced, then Maximum. Check a real page after the stronger presets, especially small type, so the file you send is one you have looked at.

Why did Light give me the original file?

Because the packed copy was the same size or heavier. Light returns the original in that case, so you are left with the lighter file. That is a useful result: the document was already compact. Move to Balanced if you still need fewer bytes, and measure the new download the same way.

What is the difference between Balanced and Maximum?

Both redraw the pages as images. Balanced uses quality 0.72. Maximum uses quality 0.55, so it pushes the file smaller and asks you to look a little harder at fine print. Run Balanced first. Use Maximum when the size still needs to drop, and keep the version that stays readable.

How do I tell whether the PDF is small enough?

Read the size of the download you downloaded and compare it with the limit of the form or the inbox. Then open a page. If both the number and the page are acceptable, send that file. If the number is still high, try the next preset and measure again. The check is the download in front of you.

What should I know before I compress a long PDF?

You get a smaller PDF you can check, by trying a preset and reading the download. Balanced and Maximum cover up to 200 pages on the raster path. On the server path, free files are 12 MB and eight a day, and Pro is 100 MB. Compare the saved file with the size you had in mind.

You need a smaller PDF, and you want to see the real file size before you send it. Pick Light, Balanced, or Maximum, download, and check the number on the file you actually got. Light, Balanced, and Maximum are the three strengths. Light repacks the PDF with object streams. When that packed copy is the same size or heavier than the download you started with, Light gives you the original back, so you keep the lighter of the two. Balanced and Maximum redraw the pages as images, Balanced at quality 0.72 and Maximum at quality 0.55, which is why they can take a large scan down further. After each run, look at the download size. If it is still heavier than the place you need to upload it, try the next preset. You are steering by the file you can measure, one honest step at a time. Open a page after you compress, especially after Maximum. Small type and a faint signature deserve a glance, because a stronger preset redraws the page and the goal is a file that is both lighter and still readable. If Light was enough, stop there and keep the sharper document. If Balanced lands in the range you need, you can skip Maximum. Save the version that passes your size check and still looks like the document you meant to send. That habit, preset then a look at the download, is how you get a smaller PDF you can trust.

A smaller file you can measure

Bring the PDF, try a preset, and read the size of the download before you send it anywhere. Light is the gentle first pass: it repacks the file with object streams and hands back the original when the new copy is heavier or unchanged, so you are never stuck with a larger file from that pass. Balanced and Maximum go further by redrawing the pages, at quality 0.72 and 0.55. They are the presets to try when Light left the file above the limit a form or an inbox set. Compare the three downloads if you need to, and keep the lightest one that still reads well. A signature, a table, and any small print should be checked on the preset you plan to use. The useful result is a PDF whose size you have seen with your own eyes.

Start with Light and keep the lighter file

Light is the preset to run first when the PDF is already mostly text and you hope a tidy repack is enough. It uses object streams to pack the file. If the packed result is smaller, that is your download. If the packed result is the same size or heavier, you get the original back, so the download you save is the lighter one. Check that size. Plenty of digital documents shrink enough on Light, and you keep the pages as they were. When the number is still too high for the upload, move to Balanced. You have lost nothing by looking, and you know the real size instead of guessing.

Balanced, then Maximum, if you need to go further

Balanced redraws the pages at quality 0.72. Maximum redraws them at quality 0.55. That redraw is why a scan or a photo-heavy PDF can drop more on these presets than on a simple repack. Run Balanced, check the download size, and open a page of small type. If the file is light enough and the page still reads, stop. If you need it smaller, run Maximum and look again. Stronger is useful, and it is also the moment to be kind to a signature or a footnote. Keep the preset that satisfies the size and still looks like your document. The download in front of you is the measurement that matters.

Judge the file you downloaded

After every preset, read the size of the saved PDF and open it. You are looking for two things: a number that fits where the file is going, and pages you can still read. If Light surprised you by being enough, use Light. If Maximum is the one that fits, use Maximum and accept the redraw that got you there. Name the file so you can tell the presets apart while you compare. Then send the one you checked. A smaller PDF is a success when you have seen both the size and a real page, and this page is built so you can do exactly that.

How it works

1
Add the PDF and try Light
Start with Light. It repacks the file with object streams and returns the original if the packed copy is the same size or heavier. Download and read the file size.
2
Step to Balanced or Maximum if needed
If Light is still too heavy, run Balanced, which redraws pages at quality 0.72. If you need to go further, run Maximum at quality 0.55. Check the size after each one.
3
Open a page, then send the file that fits
Read a page of small type or a signature on the preset you plan to keep. Save that download. The size you saw on the file is the size you can plan around.

Use cases

An upload with a size ceiling

Try Light, check the download, and move to Balanced or Maximum until the file fits the ceiling. Send the version you actually measured.

A scan that is heavier than the text

Photo pages often shrink more when they are redrawn. Balanced at 0.72 or Maximum at 0.55 is the path to try after Light, with a look at readability.

A contract you still need to read

Prefer the gentlest preset that meets the size. Light keeps the lighter file. Step up only if the number says you still need to.

Problems we solve

Light barely changed the size

The packed copy was close to the original, so Light kept the lighter file. Move to Balanced and check again. The next preset is how you ask for a smaller download.

Maximum is small but hard to read

Quality 0.55 redraws the pages more aggressively. If a signature or footnote suffers, go back to Balanced at 0.72 and see if that size is acceptable.

Trust & privacy

You keep the lighter Light pass

Light uses object streams and returns your original when the new file is the same size or heavier. The download from that preset is the smaller one.

The size is on the download you save

Every preset ends in a download you can measure. Compare Light, Balanced, and Maximum by that number, and by a page you open, before you send anything.
