Compress a PDF on iPhone without an app
The file is on your phone, the portal or the mail app refuses it for being too big, and you would rather not install an app for one document. Open this page in Safari, pick the file from the Files app or from WhatsApp, and compress it in the tool below. The work happens inside the iPhone's own browser, so nothing is uploaded to a server, there is no account and no daily limit, and the service is completely free.

Files are processed on your device and never uploaded
Runs in your browser. Your file never leaves your device.
You can process several files at once, up to 3.
From Files, WhatsApp, or Mail into the tool in Safari
The file you want to compress is in one of three places on an iPhone. If it is already in the Files app, open this page in Safari, tap the tray above, choose Browse, and go to the folder. If it arrived on WhatsApp, press and hold it, choose Share, then Save to Files, and come back to this page to pick it. If it is a mail attachment, tap the attachment, tap the share button, then Save to Files. The path is the same in all three cases: the file lands in the Files app on your device first, and from there you select it in the tray. There is no sign-in and no intermediate step, and the same method works in Safari, Chrome, and Firefox on iPhone, on an iPad, and on Android phones by the same logic.
Why you do not need an App Store app
PDF compressors in the App Store take space on the device, many of them upload your file to a distant server to do the work and send it back, and some show ads or ask for a subscription after the second file. What is here is a web page: you open it, use it, and close it, with nothing left installed. The compression itself runs inside the browser on the iPhone's own processor, which means the file never leaves your device at any moment, and there is no copy on our side or on any third party's. That difference is not cosmetic when the file is a bank statement, a contract, or a photo of an ID. There is no account, no email address, and no daily file limit, and Khallas is completely free.
Which level to pick on a phone, and what changes
The tool gives you three levels and no box for typing a target size, because how much a file shrinks is decided by what is inside it, not by a number you ask for. The light level rewrites the file's structure, keeps text selectable and searchable, and preserves fonts and links, with a modest saving. Medium and strong redraw every page as an image, which gives the biggest saving on scanned documents and phone photos but removes the text layer. The practical rule on a phone: if the file is a scan or photos, choose strong; if it is a text document you need to copy from or search, choose light. The result card shows the size before and after, so you read the difference yourself before downloading anything.
Sending the compressed file back to WhatsApp or Mail
When compression finishes you get a download button and a share row beside it. On devices whose browser can hand a file to another app, which includes the iPhone, that row carries a button that opens the familiar iOS share sheet, so you pick WhatsApp or Mail or any other app and the compressed copy itself is handed straight over without a detour through the Files app. That is the fastest route on a phone. If you prefer the longer way, tap download and Safari saves the file to the Downloads folder in the Files app, from where you send it like any other attachment. If WhatsApp is specifically the destination, there is a page here about its limits and what works with them, linked in the related pages list below.
Offline, and on the home screen as an app
The tools run inside the browser, so once their code has reached your device they need no network to work. The offline page saves a copy of the code for every tool, its fonts, and its pages in both Arabic and English, after which you can cut the connection and compress a file on a plane or in a building with no signal. Once that copy is saved you can add Khallas to your home screen from the share button in Safari, then Add to Home Screen, and it opens as an app in its own window with no address bar. Plainly: use-case pages and the blog are not part of the saved copy, since the tools are what the copy is for, and Arabic OCR needs a recognition engine that downloads on first use and is deliberately left out so the download stays small.
Limits worth knowing before you start
Three things deserve saying. First, a password-protected file refuses to open and the page tells you so; the fix is to remove the protection with the unlock PDF tool if you know the password, compress the result, then protect it again if it has to arrive locked. Second, a text file that is already well compressed can come out larger than it went in at the medium and strong levels, because those turn pages into images, and the result card warns you when that happens so you keep the original. Third, compression runs on the device's memory, so a file of several hundred pages on an older iPhone can be slow; split it with the split tool and compress each part on its own. HEIC photos from the iPhone camera belong to the images-to-PDF tool rather than this one, and need saving as JPG first.

Compare the before and after sizes, then download the file or hand it straight to WhatsApp from the share row
Frequently asked questions
Do I need an app from the App Store?
No. You open the page in Safari and pick the file from the Files app or from a WhatsApp share, and the compression runs inside the browser on your device.
Does it work offline?
Yes, once you save a copy from the offline page. After that the tools run with no connection and the site can be added to the home screen, because the processing happens on the device.
Where does the compressed file go on an iPhone?
To the Downloads folder in the Files app, from where you share it on WhatsApp or Mail or upload it to any portal. Or hand it straight to the app from the share button under the result.
Is my file uploaded to a server?
No. The file stays on the iPhone throughout, and there is no copy of it on our side.
Does it work on iPad and Android too?
Yes, the same way in any modern browser on an iPad, an Android phone, or a computer.
Can I compress a password-protected PDF on an iPhone?
Not directly; an encrypted file refuses to open and the page says it is protected. Open it with the unlock PDF tool if you know the password, compress the result, then protect it again if needed.
Why did the file come out bigger after compressing?
Because it is a text file that was already well compressed, and the medium and strong levels turn pages into images, which adds size. Try the light level; the result card warns you when a file grows so you keep the original.
