Free construction takeoff software, honestly reviewed

Free construction takeoff software exists in two real forms: a capped free plan (STACK's keeps one active project a month and 50 measurements per project¹) and free PDF editors with measuring tools, such as PDF-XChange Editor, that measure length and area on any plan with no project limit². Everything else is a trial of 7 to 14 days³⁴. Free tools measure well but don't count symbols for you, so on a large set the hours add up fast.

Construction takeoff software free options, by what you give up

A takeoff is the list of quantities pulled from the drawings: items counted, runs measured, areas calculated. Free tools differ in which of those they help with and what limit they put on you. Facts below come from each vendor's page, checked November 3, 2026.

Free PDF takeoff software: what the measuring tools can do

Most plans arrive as PDFs, so the most useful free takeoff software is a PDF editor with measuring tools. PDF-XChange Editor's feature list marks distance, perimeter and area measurement annotations as free features². Adobe Acrobat has the same three tool types, and when you measure it shows the scale ratio in a Measurement Info panel and inserts the values as comments⁶. That covers the measured half of a takeoff: conduit and cable runs, wall lengths, floor areas.

What neither free tool gives you is a count tool that finds symbols. You can place a stamp or a small shape on each device and count the marks, but you are still clicking every one. For trades where most of the takeoff is counts, like electrical, low voltage or fire alarm, that is the slow part.

How to do a takeoff with free PDF tools

Confirm the set. Check the sheet index and the latest addenda before you measure anything. Measuring a superseded sheet is the most expensive free mistake there is.
Calibrate the scale on every sheet. Use the calibrate option to set the scale from a dimension printed on the drawing, not from the scale note alone; plans get printed to fit. Then measure a second known dimension somewhere else on the sheet. If the two disagree, stop and find out why.
Watch for multiple scales. Enlarged plans and details on the same sheet often use a different scale from the main plan. Recalibrate before measuring in a detail.
Count by type, one type at a time. Pick one symbol from the legend, mark every instance on the sheet with the same stamp or color, and write the total into a takeoff sheet. Then the next type. Counting several types in one pass is how items get missed.
Measure runs with polylines. Use the perimeter tool for runs with bends, and add vertical drops and rises separately; a plan view shows none of them.
Record quantities per sheet. Write each count and length into a row per item per sheet. Our free electrical takeoff sheet is laid out that way, so totals and sheet-by-sheet checks come out of the same table, and the other estimating templates pick up from there.
Handle typicals and keyed notes. A room drawn once and marked “typical of 6” gets counted once and multiplied in the sheet, with a note. Devices called out in notes but not drawn get added by hand.
Check against schedules. If there is a fixture or equipment schedule, compare your totals with it and find the sheet behind any difference.
Save the marked-up PDF. It is your audit trail when a question comes back during the bid or after award.

Where a free takeoff breaks

Counting at scale

Clicking every device works on a 4-sheet tenant improvement. On a 60-sheet building it turns into days, and accuracy drops as attention does. This is the main reason estimators pay for takeoff software.

No totals across sheets

Free PDF tools measure page by page. Adding up a count across 30 sheets means a spreadsheet and careful transcription, and a typo there is invisible until the supplier quote disagrees. A workbook built with SUMIFS and check cells catches some of it.

Revisions

When an addendum replaces six sheets, you redo those sheets and hope you find what changed. Revision compare is a paid feature in the tools above; at Bluebeam it starts on the Core plan⁸. The Bluebeam Revu comparison lists what each plan adds.

Locked or scanned PDFs

Acrobat Reader's tools only work when the creator enabled measuring⁶, and a scanned sheet has no vector lines to snap to. Both happen on real bid sets.

Watermarks

In PDF-XChange's free version, using a licensed feature puts a watermark on the output⁵. Stick to the free measuring tools if the marked-up PDF goes to a customer.

Free takeoff software online, for Mac, and to download

Online: STACK's free plan runs in the browser¹, and zzTakeoff is cloud-based with a 14-day trial⁹. Nothing to install, which also makes them the easiest answer on a Mac.

For Mac: beyond browser tools, LibreCAD is free and open source on Windows, Mac and Linux¹¹, and Autodesk Viewer is a free online viewer for design files¹². Bluebeam Revu's desktop app is Windows, with web and mobile access on its plans⁸.

Download: PDF-XChange Editor's free version is a download, and the vendor says 70% of its features are unrestricted². Only download from the vendor's site. Easy PDF Takeoff is another Windows download built for takeoff on PDFs; the Easy PDF Takeoff comparison covers what it does, what the license costs and how it counts.

AI takeoff software free trials, and quantity takeoff in general

AI features are where vendors spend compute, so none of them are in a free plan. They are in the trials: PlanSwift's 14-day trial includes every feature and all its AI tools⁴, STACK's free account starts with 7 days of Pro¹, and Bluebeam's trial runs on its Max plan, which adds AI drawing reviews and comparisons⁷⁸. Test them on a set you already took off by hand, so you can see exactly what they missed. Our AI takeoff software guide covers how the methods differ.

For quantity takeoff across trades (areas for flooring, lengths for framing, counts for doors), the construction takeoff software guide compares the paid options. For electrical counts specifically, see electrical takeoff software.

How to get the most out of a free trial

A 7 or 14-day trial is short, and most of it disappears into setup if you go in without a plan. Treat it as a test with a known answer:

Pick a bid you already took off by hand, ideally one that was awarded, so you trust your own quantities.
Use the same plan PDF, including any messy sheets: rotated symbols, a scanned page, enlarged plans at another scale.
Time yourself from upload to finished quantities, including setup, scale and review, not just the automatic part.
Compare item by item with your manual takeoff and write down every difference and which side was right.
Export the quantities and see whether they land in your spreadsheet or estimating system without retyping.
Before the last day, check what happens to your data when the trial ends and how the paid plan is billed.

At the end you have a number for hours saved per bid and a list of errors, which is a far better basis for spending money than a sales demo. PlanSwift, for one, says nothing is charged automatically when its trial ends⁴; read the terms of any other trial before you start it.

Where AmpCount fits

AmpCount is not free. It is an electrical takeoff tool at $149 a month or $1,490 a year for a team of up to 3, with a full refund within 14 days, and no free plan or trial. It does the part free tools leave to you: it reads the legend on a vector PDF set and counts every electrical device and fixture on every sheet, keeps uncertain marks out of the count until you confirm them, and checks fixtures against the schedule. It doesn't measure conduit or wire, so the free measuring tools above still have a job. For the pricing half of the bid, see free construction estimating software.

Questions

What is the best free takeoff software?

For digital takeoff with no time limit, STACK's free plan is the only vendor plan we found that stays free after the trial, capped at one active project a month and 50 measurements per project¹. With no caps at all, a free PDF editor with measuring tools works, but you count by hand.

Can I do a takeoff in Adobe Acrobat Reader?

Sometimes. Reader has distance, perimeter and area tools, but Adobe says they work for Reader users only if the PDF creator enabled measuring⁶. If the tools are greyed out on your plans, that's why.

Is there free takeoff software for Mac?

Browser-based tools work on a Mac, including STACK's free plan, which STACK describes as 100% cloud-based¹. LibreCAD runs on Windows, Mac and Linux¹¹ if you receive DXF files. Bluebeam Revu's desktop app is for Windows; its plans add web and mobile access⁸.

Is there free AI takeoff software?

Not as a free plan. You can try AI features during trials: PlanSwift's 14-day trial includes all its AI tools, and STACK's free account starts with 7 days of Pro⁴¹. Togal.AI lists no free plan¹⁰, and Kreo's automatic symbol counting is on its paid Pro plan with a 7-day trial³.

Is AmpCount free takeoff software?

No. AmpCount is a paid electrical takeoff tool: $149 a month, or $1,490 a year, for a team of up to 3, full refund within 14 days, no free plan or trial. Our takeoff sheet and calculators are free.

Count the devices, check the numbers

AmpCount reads the legend on a vector PDF set, counts every electrical device and fixture on every sheet, keeps uncertain marks out of the count until you confirm them, and checks fixtures against the schedule. $149 a month or $1,490 a year for a team of up to 3, cancel anytime, full refund within 14 days.
