Optimizing one PDF at a time is fine until you have a folder of them.
Loading Optimize PDF…
Upload several PDFs and optimize them in one run
Each file is rebuilt independently and losslessly
Download the optimized set together when it finishes
Encrypted upload, files auto-deleted after processing
Drop the Optimize PDF into a blog post, product docs, intranet, or school portal with one iframe. Processing, privacy, and usage limits are the same as on the full tool page.

Batch optimization earns its keep whenever PDFs arrive in volume and follow a similar shape. Accounting teams handle streams of invoices and statements. Operations teams archive scanned delivery notes and signed forms. Publishers and product teams manage libraries of sheets and manuals. In every one of these cases the files share the same kind of export bloat, and processing them together clears it from the whole set in a single pass instead of a hundred separate ones.
Because each file in the batch is optimized independently, a single oversized or unusual document does not hold up the rest, and the reduction on each reflects that file own overhead. A clean invoice might shrink only slightly, while a scanned form full of duplicated resources drops more. The lossless nature of the process means you do not have to open every result to confirm nothing was degraded, which is what makes bulk optimization safe to run unattended on documents you care about.
If your batch is mostly scanned or photographic and you need a much larger reduction, remember that lossless optimization protects the images and therefore has a ceiling. The PDF Compressor supports the same multi file workflow and will cut image heavy sets far more, with a small quality tradeoff. Many teams run optimization on their text based documents and compression on their scanned ones, choosing the tool per file type.
Select multiple PDFs in the upload step and run Optimize PDF to process them as a batch. Download the optimized files individually or all at once when the run completes.
Step-by-step guide to batch optimize multiple pdfs:
Open Optimize PDF
Launch the FixTools Optimize PDF tool in your browser. No install or account is needed.
Select multiple PDFs
In the upload step, choose several files at once, or drag a group of PDFs onto the upload area. They upload over an encrypted connection.
Review the file list
Check the list of selected files and remove any you did not mean to include before running the batch.
Optimize the batch
Click Optimize to process every file. Each PDF is rebuilt on its own, so one heavy file does not affect the others.
Download the results
Save the optimized files individually or use the download all option. The processed copies are deleted from our servers automatically.
Common situations where this approach makes a real difference:
Monthly invoices
An accounts team optimizes a month of invoice PDFs in one batch before filing them, trimming the export overhead across the whole set in a single run.
Scanned records
An operations coordinator uploads a folder of signed delivery notes and optimizes them together for the archive, keeping every scan legible.
Product sheet library
A product team refreshes a library of spec sheets and batch optimizes the new exports before publishing them to a partner portal.
Report archive
A analyst archives a quarter of reports and slims them all at once to keep the shared drive tidy without opening each file.
Get better results with these expert suggestions:
Group files by type
Batch your text based PDFs through the optimizer and your scanned or photo heavy ones through the compressor, so each set gets the right treatment.
Prune the list before running
Remove any stray files from the upload list first, so the batch only processes what you actually want.
Use download all to save clicks
When the run finishes, the download all option saves the whole set at once instead of clicking each file.
Keep originals until you verify
Hold on to the source files until you have spot checked a few results, then archive the optimized versions.
