Edit, compress, or tweak any image
Open the editor on any thumbnail to crop, rotate, adjust or annotate. Use the global quality and size controls, or override settings per image. The estimated final PDF size updates live.

Why use Image to PDF Converter?
100% private
All conversion happens locally in your browser using JavaScript. Your images are never uploaded, stored or seen by anyone.
Real compression control
Most converters give you a single “quality” toggle. Here you control quality, maximum resolution, output format and even a target file size — globally or per image — and see the estimated size before you export.
Built-in image editor
Crop, rotate, flip, adjust brightness/contrast, apply filters, add text or annotations and watermark — without leaving the page.
Works on any device
No install and no account. It runs in any modern browser on Windows, macOS, Linux, Android or iPhone.
Combine any image format into one PDF
You can mix formats freely in a single document — a JPEG photo, a PNG screenshot, a HEIC shot from your iPhone and a WebP graphic can all become pages of the same PDF. Each image is placed on its own page, and you decide the order by dragging the thumbnails. This makes LocalTools handy for assembling receipts, ID scans, homework, contracts or a quick photo album into one file you can email or print.
Why convert images to PDF?
A PDF keeps your images together in a fixed order, opens identically on every device, and is far easier to share or archive than a folder of loose files. Converting also lets you shrink large camera photos so the final document fits under email and upload limits. Because LocalTools compresses and builds the PDF locally, you get those benefits without handing your pictures to a third-party server.
When a folder of photos isn’t enough
Sending ten photos as separate attachments is messy for the recipient and often hits size limits. A single PDF arrives as one clean file, preserves your intended order, and works reliably in email clients, filing systems, court submissions, school portals and print shops. The thumbnails in the tool let you visually confirm the sequence before you commit.
Compression that respects your originals
Camera photos are often 5–15 MB each. The built-in controls let you set a global quality and max resolution, then fine-tune any single image that needs to stay sharper. The live size estimate updates so you can hit an email-friendly target (under 5 MB or 10 MB) without guessing. Because everything happens locally, you can iterate quickly without re-uploading.
Guides & explanations
You don’t need a scanner — you need decent light, a steady phone and the right way to turn the photos into a small, ordered, shareable PDF. Here’s the whole workflow.

Read the guide →Frequently asked questions
Are my images uploaded to a server?
No. Every step — decoding, editing, compression and PDF creation — runs entirely in your browser. Your files never leave your device, which is why it works even offline once the page has loaded.
Which image formats are supported?
JPG/JPEG, PNG, WebP, GIF, BMP, AVIF and SVG are read natively. HEIC/HEIF photos from iPhones are converted automatically. You can mix different formats in a single PDF.
How do I make the PDF smaller?
Lower the quality slider, reduce the maximum resolution (e.g. 1600px), choose JPEG output, or set a target size in megabytes. You can apply these to all images at once or override a single image. The estimated output size updates as you change settings.
Is there a limit on how many images I can convert?
There is no fixed limit. Because conversion runs on your own device, the practical limit is your device’s memory — hundreds of typical photos work fine.
Does it cost anything or add a watermark?
No. LocalTools is completely free and never adds a watermark to your PDF.
