How it works
How to convert images to PDF
Turn JPG, PNG, and WebP photos into one PDF — free, in your browser. Add multiple images, pick a page size (A4, Letter, Legal, A3, or fit-to-image), drag to reorder, and download a shareable PDF.
Perfect for receipts, photo albums, ID scans, and homework photos you need to email as a single attachment.
Cameras and phones capture JPG (and PNG/WebP). Institutions still ask for PDF. That mismatch shows up everywhere: expense portals that reject loose photos, school portals that want one homework file, landlords who want a single move-in condition packet, travel desks that demand ID scans as PDF, and clinics that accept photo documentation only inside a document upload slot. LokaPDF converts images to PDF entirely in your browser—add multiple photos, choose a page size (A4, Letter, Legal, A3, or fit-to-image), drag thumbnails into order, and download a shareable document without uploading your pictures to a third-party converter.
Page size choice changes the look of the result. Fit to image keeps phone photos from sitting in odd white frames when aspect ratios vary. Fixed sizes like A4 or Letter help when a portal expects a standard sheet for printing or archival. Order matters as much as pixels: put cover or ID first, then supporting shots, then receipts. Because processing is local, passport photos, signed forms, and desk scans never need to cross the network for conversion. There is no watermark on the free download and no soft-crop step that silently trims edges—you control framing in the camera or editor before you convert. What you add is what becomes a page.
Image quality in equals image quality out, within PDF page embedding. Blurry phone shots stay blurry; sharp scans stay sharp. For HEIC from iPhones, export to JPG first—the web tool does not read HEIC directly. Mixed PNG screenshots and JPG photos can live in one PDF; use consistent orientation when you can so readers do not rotate mid-scroll. Straighten skewed desk photos before conversion if edges must look square. If the finished album is too large for email, open Compress PDF next rather than re-photographing everything at lower quality. Need the reverse later? PDF to JPG exports pages back to images when a channel wants pictures instead of a document.
Think of JPG-to-PDF as packaging, not editing. Crop, straighten, and expose-correct in your photo app first if the subject must be clear. Then convert so recipients get one attachment with a stable page order. That habit saves back-and-forth when someone replies “please send as PDF” and you already have the photos ready on the device. It also avoids the privacy mistake of uploading a whole camera roll subset to an unknown “free JPG to PDF” host just to satisfy a form field.
LokaPDF keeps the loop short: select images, set size and order, convert locally, download. No account, no install, and no requirement to park personal photos on a remote merge server. When you need more pages later, convert a new batch and merge with Merge PDF, or rebuild from the original images if order must change. The originals remain the source of truth; the PDF is the shareable package. That separation also helps when a portal rejects the first attempt—you adjust size or compression without re-photographing the scene.
Email and print workflows benefit from the same habit. Convert once, open the PDF on desktop and phone, confirm page order and orientation, then attach. If a printer crops edges, switch to a fixed page size and leave a little margin in the photos. If a portal wants fewer megabytes, compress after conversion rather than lowering camera quality first. Those small checks turn a camera-roll dump into a professional attachment that recipients can open without special apps.

Why browser processing & tips
Why process PDFs in your browser?
Most PDF sites upload your file to a remote server first. That adds wait time, queueing, and means your document passes through infrastructure you do not control. LokaPDF converts images to PDF entirely in your browser — file content is not uploaded to our servers. HEIC/iPhone photos must be exported to JPG first — the web tool does not read HEIC directly. The tool works on Windows, Mac, Linux, iPhone, and Android with no install.
Expense receipts, scanned signatures, portfolio photos, or merging screenshots into one document for submission. People convert receipt strips for monthly expenses, homework photos into single submit files, apartment condition photos for leases, clinic paperwork shot on a phone into one upload, portfolio boards into client leave-behinds, and whiteboard snapshots into meeting follow-ups. Field teams turn inspection photos into PDF reports; students combine worksheet pictures with a cover page; freelancers package mockup screenshots for approval. Real-estate agents assemble listing photo sets; warehouse staff document damaged shipments as PDF claims. Parents combine school forms photographed on a phone into one packet for the office. Insurance claimants gather damage photos into a single adjuster-ready PDF. Whenever the source of truth is a camera roll but the destination is a PDF slot, browser-local conversion avoids uploading private images to an unknown converter queue—and keeps page order under your control before anyone else opens the file.
Tips
- Fit to image avoids white borders on vertical phone photos.
- Compress the PDF afterward if the album is too large for email.
- Use Fit to image for mixed phone photos to reduce awkward letterboxing on tall shots.
- Drag thumbnails into final order before converting—fixing order in email threads is harder than fixing it here.
- Export HEIC to JPG on iPhone before adding files; unsupported formats will not appear as pages.
- Compress the PDF afterward if portal or mailbox limits reject the album size.
- Prefer well-lit, sharp captures for IDs and forms—conversion does not sharpen soft photos.
- Keep originals until the recipient confirms the PDF; regenerating from images is straightforward if a page is missing.
