Inspection Report PDF Too Large? Shrink Photo-Heavy Reports on a Mac

Because every photo is a full-resolution JPEG inside the PDF. A report with 150 findings and one photo each carries 150 images, and a modern phone photo is a 12 megapixel frame. The words, checkboxes and logo barely register in the total.

That is why a photo-heavy PDF behaves differently from a text document. Squeezing the text does nothing; shrinking the pixels does everything. Two levers exist. You can shrink the photos before the report software places them, or you can shrink the finished PDF afterward. The first gives you control over each image. The second is faster when the report is already built and the client is waiting.

One caution for later: PDFs made by some generators compress by almost nothing, and scanned pages or exports from design tools compress well. Compress one report, look at the number, and only then batch the rest. The same logic applies to a scanned appraisal, covered in our guide to compressing a scanned PDF on a Mac.

Most senders stop at 25 MB, but the receiving side often stops lower. Check the limit, then aim below it, because mail servers measure the encoded message, which adds about 37% to a file.

The 37% encoding figure comes from Google’s own footnote, quoted in our post on getting a PDF under Gmail’s 25 MB limit. Divide the cap by 1.37: a 25 MB cap means about 18 MB on disk. If you do not know the recipient’s limit, aim at 7 MB. When the report is still too big, a link is the honest answer: a cloud-storage link, or Mail Drop if the client can open a link.

There is no single national number. The lender, the appraisal management company or the review portal sets it. One published figure is Freddie Mac’s: 125 MB per individual QC upload and 100 MB for bulk.

Freddie Mac’s same spec says to provide documents in one PDF, and it names appraisals when it says documents must not carry primary or secondary passwords. It also asks that security settings allow all actions. A compressed copy that you password-protect afterward could be refused. Other lenders and appraisal management company portals set their own caps, so read the upload screen, or ask the desk that ordered the appraisal. If it names a number, write it on your delivery checklist once.

Appraisers hit the cap too: many photos plus a sketch plus supporting addenda in one file. The fix is the same as for an inspector, and it works on lender-facing PDFs before they go out. If you also work with lenders, our page for mortgage loan documents covers the file-heavy end of that chain.

Resize and compress the photos first, then import them. A 4032 by 3024 frame fitted inside 1600 pixels keeps about 16% of the pixels, which is plenty for a roof, a panel or a crawlspace on a laptop or a phone screen.

Quality belongs to Compress. Converting HEIC to JPG ignores the quality setting and writes a large file, so for phone photos use Compress with JPG output. On 24 small test photos (768 × 512 film frames, high-quality JPEGs), Smol’s default JPEG pass made them 69.3% smaller. Camera files will differ; the method is on the benchmark page.

Drop the PDF into Smol and pick a preset. The five presets cap the longest edge of each embedded image at 600, 900, 1200, 1800 or 2400 pixels for Tiny, Small, Medium, Large and Original. They are pixel caps, not DPI targets, so the effective resolution depends on how big the photo prints on the page.

• Small is the email preset: 900 px per image. Start here.
• Medium at 1200 px suits a report where the client zooms in or a scanned appraisal. See what the presets actually do.
• Original is not lossless. It re-encodes and resamples anything above 2,400 px.
• No preset strips document properties. Use the metadata operation for that, and read our note on PDF metadata: the result can be reversible unless the file is rewritten afterward.

The output is a copy next to the original with a _compressed suffix, so your archive copy of the delivered report is untouched by default. If compressing would make a file larger, the direct compress path keeps the original. Smol does not edit, merge, split, sign or redact PDFs, and it does not run OCR, so a report with a text layer stays as the report software made it.

1. 1

   Save a full-size copy

   Keep the original report in your job folder. Smol writes a copy with a _compressed suffix and does not overwrite by default.

2. 2

   Drag the PDF into Smol

   Several reports can go in at once, and mixed batches of PDFs and photos are fine.

3. 3

   Choose Small

   Run it and read the size Smol shows for the output. Smol sets image size and quality, not output bytes, so check the number against your limit.

4. 4

   Look at three pages

   Open the compressed copy and zoom on the page with the smallest defect photo. If the detail is gone, rerun the original at Medium.

5. 5

   Send, or send a link

   If the file is under about 18 MB, attach it. If not, share a link instead of compressing a third time.

Try the free routes first. Your report software may have an image-quality or photo-size setting; check before buying anything. Where it does not, here is how the options compare.

Our post on Preview’s Reduce File Size shows where the built-in route fails. For a one-off, the free options are fine; Smol earns its price when you send reports every week. If you also shoot listing work, see real estate listing photos and our page on insurance claims photos.

• You need a pixel-identical file: Smol always re-encodes images and has no lossless mode.
• You need to redact names, edit or sign a report: Smol does neither.
• The report is a text-only PDF from a generator that barely compresses: little will change.
• Your report software already has a photo-size setting that gets you under the cap.
• You are on Windows or Linux: Smol is Mac only. A team can recreate the same settings on each Mac, but presets live on one Mac.

Teams and pricing

Solo is $29 once for one Mac. Team is $49 once for three Macs, and Enterprise is $20 per seat for 5 to 500 seats. A five-person firm buys Team plus Solo, or five Enterprise seats. See pricing. There is no free trial and purchases are not refundable.
