How do I merge multiple PDFs into one PDF?

Drop the PDFs onto the page, drag the cards to set the output order, optionally rotate or pick a page range for each, then click Merge into one PDF. The merged file downloads to your device immediately - nothing is uploaded.

Can I mix images and PDFs in the same merged file?

Yes. Drop any combination of PDFs and images (JPG, PNG, WebP, HEIC, GIF, BMP, SVG). Each image becomes one page; each selected PDF page is copied in. The cards keep their dropped order until you drag them.

Are my files uploaded to a server?

No. The merge runs entirely in your browser using WebAssembly. Your files never leave your device - the page works offline once it has loaded, and you can verify this in your browser's network panel.

How do I reorder PDF pages before merging?

Each file is a draggable card. Click and drag the handle on a card (or press Tab to focus it and use Space + arrow keys) to move it to a new position. The merged PDF reads top-left to bottom-right in the order shown.

Can I select specific pages from a PDF instead of merging all of it?

Yes. Multi-page PDFs show a 'Pages' field on their card. Type a comma-separated list with ranges - for example 1-3,5,7-9 - and only those pages are included in the merged output, in the order you specified.

Can I rotate pages before merging?

Yes. Every card has rotate-left and rotate-right buttons that step by 90 degrees. The thumbnail rotates live so you can preview the result. Image cards rotate the bitmap before embedding; PDF cards apply the rotation to the embedded page.

Does merging compress or re-encode the source PDFs?

No - the source PDF pages are embedded as-is, preserving the original page content stream. Images are embedded losslessly (JPG bytes are kept verbatim when rotation is 0; other formats are encoded as PNG, also lossless).

What page sizes are supported?

Auto (each page sized to its content for a zero-whitespace PDF), A4 (210x297mm), Letter (8.5x11in), and Legal (8.5x14in). Combine any size with portrait, landscape, or auto orientation, and pick a margin of None, 0.25in, 0.5in, or 1in.

Can I merge HEIC photos from my iPhone?

Yes. HEIC files are decoded locally by a WebAssembly module, converted to a canvas, and embedded into the merged PDF. Drop them alongside any other image or PDF.

Is there a file size or count limit?

No server-side limit - the tool never uploads anything. A warning shows when the total exceeds 200 MB because very large batches can stress browser memory, especially on phones. Most users can comfortably merge dozens of files at a time.

Does this work on iPhone, iPad, or Android?

Yes. The interface is responsive and the drag handles use touch-aware pointer events. Safari 16.4+ on iOS, Chrome on Android, and any modern mobile browser are supported.

Can I password-protect the merged PDF?

Not directly from the merge tool today. After downloading the merged PDF you can add a password with any PDF security app, or open it in Preview (macOS) / Acrobat to set permissions.

Will the merged PDF keep clickable links and bookmarks from the source PDFs?

Embedded page content (text, links inside the page) is preserved. Outline-level bookmarks from the source PDFs are not carried over to the merged document - this is a limitation of the browser-side merge.

Why use this instead of a desktop PDF merger?

No install, no signup, and your files never leave your computer. The tool is also reordering-first, which most desktop apps treat as a secondary feature - here drag-and-drop is the primary interaction.

PDF'lar va rasmlarni bitta PDF'ga birlashtirish

Bir nechta PDF va rasmlarni bitta PDF fayliga birlashtiring. Qayta tartiblash, aylantirish va har qanday PDF uchun sahifa diapazonlarini tanlash uchun torting. Hammasi brauzeringizda sodir bo'ladi - fayllaringiz hech qachon qurilmangizni tark etmaydi.

Fayllar brauzeringizni hech qachon tark etmaydi. Barcha ishlov berish qurilmangizda ishlaydi.

Rasmlar yoki PDF'larni bu yerga tashlang yoki ko'rish uchun bosing

JPG, PNG, WebP, HEIC, GIF, BMP, SVG va PDF qo'llab-quvvatlanadi

Qanday ishlaydi

Fayllar papkasidan bitta, tartiblangan PDFgacha to'rt qadam - butunlay brauzeringizda.

1. Fayllaringizni qo'shing
PDF va rasmlarni sahifaga torting yoki tashlash zonasini bosing. JPG, PNG, WebP, HEIC, GIF, BMP, SVG va PDF kiritishlari qabul qilinadi.
2. Qayta tartiblash, aylantirish, qirqish
Chiqish tartibini o'zgartirish uchun kartalarni torting. Har qanday elementni 90° qadamlarda aylantiring va ko'p sahifali PDF-lar uchun faqat shu sahifalarni saqlash uchun 1-3, 5, 7-9 kabi diapazonni kiriting.
3. Chiqish sozlamalarini tanlang
Sahifa o'lchamini (Avto, A4, Letter, Legal), yo'nalishini va chekkasini tanlang - yoki har bir fayl mazmuniga mos keladigan nol bo'shliqli PDF uchun hammasini Avto holatida qoldiring.
4. Birlashtirish va yuklab olish
Bitta PDFga birlashtirish tugmasini bosing. Brauzeringiz yakuniy hujjatni yaratadi va uni avtomatik ravishda yuklab oladi - odatda bir necha soniya ichida.

PDF birlashtirish nima?

PDF-larni birlashtirish bir nechta manba hujjatlarini - PDF-lar, rasmlar yoki ikkalasining aralashmasini - har bir kiritma o'zingiz boshqaradigan tartibda o'z sahifasiga (yoki sahifalariga) tushadigan bitta PDFga birlashtirishni anglatadi. Natijada, sahifalar tartibsiz kelishi yoki ajralib ketishidan xavotirlanmasdan yuborishingiz, arxivlashingiz yoki chop etishingiz mumkin bo'lgan bitta fayl hosil bo'ladi.

Ko'pgina onlayn PDF birlashtirgichlar fayllaringizni yuklashga majbur qiladi. Bu boshqa birovning serverida nusxalar yaratadi, hatto qisqa muddatga bo'lsa ham, bu shartnomalar, kvitansiyalar, ID skanerlari yoki uchinchi tomonga bermoqchi bo'lmagan boshqa narsalar uchun muammo. Subformerning birlashtirish vositasi butun quvur liniyasini - HEICni dekodlash, sahifa eskizlarini renderlash, sahifalarni joylashtirish, yakuniy PDF baytlarini yozish - brauzeringizda ishga tushiradi. Birlashtirish paytida tarmoq panelini oching va serverlarimizga nol so'rovlarni ko'rasiz.

Biz qayta tartiblash va sahifa diapazonini tanlash atrofidagi ish jarayonini qayta qurdik, chunki ko'pchilik birlashmalar aslida shu yerda vaqt oladi: birlashmaning o'zi emas, balki qaysi sahifalarni qaysi tartibda kiritishni aniqlash. Tortib-tashlash asosiy imo-ishora, klaviatura orqali qayta tartiblash qo'llab-quvvatlanadi va jonli eskizlar har bir kartaning nimani anglatishini aniq ko'rsatadi.

Umumiy foydalanish holatlari

Odamlar odatda nimani birlashtiradi - va nima uchun qayta tartiblash imkoniyatiga ega brauzer tomonidagi vosita muqobillardan tezroq.

Xarajat hisobotlari
Telefoningiz bilan olingan cheklarni (HEIC, JPG) va bank PDF-larini moliya uchun bitta ilovaga birlashtiring. Eksport qilishdan oldin sanasi bo'yicha tartiblangan skanerlarni to'g'ri tartibga qo'yish uchun torting.
Ko'p sahifali skanerlar
Skaner ilovalari ko'pincha har bir sahifa uchun bitta rasm chiqaradi. Rasmlarni bu yerga tashlang, agar sahifalar aralashib ketgan bo'lsa, qayta tartiblang, gorizontal tasvirlarni aylantiring va baham ko'rishga tayyor bitta A4 yoki Letter PDF faylini yuklab oling.
Shartnomalar va imzolangan sahifalar
Imzolanmagan shartnoma PDF-ni imzo sahifalari fotosuratlari bilan birlashtiring. Butun shartnomani qayta chop etmasdan, ma'lum bir imzolangan sahifani asl nusxaga qaytarish uchun sahifa diapazonlarini tanlang.
Akademik topshiriqlar
Yozilgan hisobotni (PDF), rasmlarni (PNG yoki SVG) va ilova skanerlarini topshiriq portalining bitta fayl talabiga mos keladigan bitta yuklashga tayyor PDFga birlashtiring.
Sayohat hujjatlari
Pasport skaneri, viza, bronlash PDFlari va sug'urtani bitta hujjatga jamlang. Yetti alohida faylni qidirib yurmasdan, o'zingizga elektron pochta orqali yuborish yoki aeroportda chop etish oson.
Savdo / taklif to'plamlari
Mijozlar uchun bitta tartiblangan PDFga muqova xati PDF, mahsulot ma'lumotnomalari, keys-stadi rasmlari va narxlar sahifasini tashlang. Har safar muharriringizdan eksport qilmasdan har bir bitim uchun qayta tartiblang.

Nima uchun "brauzeringizda" muhim

Subformerning birlashtirish vositasi statik sahifa va mijoz tomonidagi JavaScriptdir. U yuklangandan so'ng, siz internetdan uzilishingiz mumkin va u hali ham ishlaydi. Siz tashlagan PDFlar va tasvirlar brauzeringiz xotirasida saqlanadi va hech qayerga nusxalanmaydi. Bu boshqa barcha Subformer fayl vositalari ishlatadigan bir xil arxitektura, va shuning uchun biz uni reklamasiz, hisoblarsiz yoki yuklash cheklovlarisiz bepul taklif qila olamiz.

Ichki mexanizm

Birlashtirishning har bir bosqichi - dekodlash, eskiz yaratish, joylashtirish, yakuniy PDFni yozish - brauzeringiz yorlig'ida ishlaydigan ochiq kodli kutubxonalar yordamida amalga oshiriladi.

Client-side PDF assembly: Chiqish hujjati sizning tabingizda yaratiladi. Mavjud PDF-dan nusxa ko'chirilgan sahifalar o'zlarining asl mazmunini saqlab qoladi, shuning uchun matn tanlanadigan bo'lib qoladi va hech narsa qayta ko'rsatilmaydi.
In-browser PDF rendering: Siz sudrab yuradigan sahifa eskizlari faqat oldindan ko'rish ruxsatida mahalliy ravishda ko'rsatiladi. Ularni yaratish uchun hujjatlaringiz hech qachon serverda rastrlanmaydi.
WebAssembly HEIC decoding: iPhone'dan HEIC fotosuratlari qurilmangizda dekodlanadi, shuning uchun ularni alohida konvertatsiya bosqichisiz birlashtirish mumkin. Brauzerlar bu format uchun mahalliy dekoderni taqdim etmaydi, shuning uchun WebAssembly moduli uni mahalliy ravishda boshqaradi.
Canvas 2D and drag-to-reorder: Tasvirlar brauzerning kanvas API orqali o'lchanadi va qayta kodlanadi, va qayta tartiblash panjarasi kirish imkoniyati uchun klaviatura orqali qayta tartiblashni qo'llab-quvvatlaydi.

Birlashtirish o'rniga bir martalik konvertatsiya kerakmi? Quyidagi har bir havola maxsus, formatga moslashtirilgan sahifani ochadi.
