Can I compress PDFs on iPhone without installing an app?

Yes. FixTools is a web app that runs entirely in Safari or Chrome on iPhone. No App Store download is needed — just open the website, upload your PDF, and compress.

Where do I find PDFs on my iPhone to compress?

PDFs on iPhone are usually stored in the Files app, iCloud Drive, or as email attachments. When the FixTools file picker opens, you can browse all of these locations.

How do I save the compressed PDF on iPhone?

After downloading, tap the share icon and choose "Save to Files" to keep the compressed PDF in iCloud Drive or on your device. You can also share it directly to WhatsApp, Mail, or other apps from the same share sheet.

Does iPhone PDF compression slow down the phone?

For small to medium PDFs (under 20MB), compression completes in a few seconds on any modern iPhone. Very large PDFs may take longer and could use significant browser memory — close other browser tabs first if you encounter issues.

Is there a free iPhone PDF compressor app?

While apps exist, they often require sign-up or add watermarks. FixTools in Safari is entirely free, watermark-free, and requires no app installation, making it the simplest option for occasional PDF compression on iPhone.
