PDF to JPG on iPhone and Android, in the browser, no app

The browser is enough

The converter on this page is not a website that forwards your file to a server. It is a PDF engine that runs inside your browser, on your phone’s own processor. That has 3 practical effects on a phone:

• No mobile data for the file. A 50 MB PDF is not uploaded and the images are not downloaded from anywhere; “Download” only saves what your phone just made. The one thing fetched is the converter itself, about 4.6 MB, with the first file.
• Works offline after the first file. Convert once, switch on flight mode, and convert the next one.
• Private by construction. A bank letter or a lease never leaves the phone, so there is nothing to trust a server with.

iPhone: Safari steps

1. Open the converter in Safari: this page, or the PDF to JPG page.
2. Tap Choose files. iOS opens its file picker (if it shows a menu first, choose the option for files, not photos); find the PDF in Recents or Browse. A PDF that came by mail: save it to Files first from the mail app’s share sheet, then pick it here.
3. Set the options. Resolution 150 for a screen, 300 for print. Type pages in Pages if you want only some, such as 1-3. Switch Several pages to “as separate files”.
4. Tap Make the images. The result shows how many pages were drawn and how long it took on the phone.
5. Tap Download next to each image. If Safari asks whether to download the file, tap Download.
6. Move them to Photos. Open the Files app, tap Browse, then Downloads (Apple’s support page “Where to find downloads on your iPhone or iPad” describes the same place). Tap an image, tap Share, then Save Image.

If you left Several pages as “as one zip”, you get 1 zip file instead. Tap it in Files and iOS unpacks it into a folder next to it (Apple’s support page “Create or open ZIP files on your iPhone” describes this); the images are inside.

Android: Chrome steps

1. Open the converter in Chrome.
2. Tap Choose files. Android opens its file picker; tap the menu for Recent, Downloads or your Drive, and pick the PDF.
3. Set the options as above, with Several pages on “as separate files”.
4. Tap Make the images, then Download next to each image.
5. Find them in the Download folder. Open Files by Google (or your phone maker’s file app) and go to Downloads, or open Downloads from Chrome’s menu. Most gallery apps also show the folder as an album.

For a zip, Google’s help for Files by Google gives the steps: select the zip, tap Extract, then Done; the images land in the same folder as the zip.

Where the files land

	iPhone (Safari)	Android (Chrome)
Downloads go to	Files, Downloads (iCloud Drive or On My iPhone)	the Download folder
Change or list them	Settings, Apps, Safari, Downloads	Chrome’s menu, Downloads
To get the image into the photo library	open it in Files, Share, Save Image	usually already there as the Download album
To open a zip	tap it in Files: a folder appears	Files by Google: select it, Extract

The iPhone row follows Apple’s support pages and the Android zip step Google’s help for Files by Google, both checked on 11 October 2026. Menu names move between system versions; if a step looks different on your phone, the place is still Downloads.

Phone limits that are real

A browser tab on a phone gets far less memory than on a laptop. The converter draws 1 page at a time, so a long document is fine as long as the file itself can be opened. When a file is too big for the phone, the tool says so with numbers: what it needs and about how much the browser has to work with. It does not just stop.

What to do when that happens:

• Convert in parts. Type 1-50 in Pages, then 51-100. Pages you skip are never drawn.
• Lower the resolution. At 300 dpi an A4 page is 2480 x 3508 pixels, 4 times the pixels of 150 dpi. For reading on a phone, 150 is plenty. 600 dpi is capped anyway: a page is drawn at no more than 16 million pixels, so an A4 page asked for at 600 comes out at 407 dpi, and the result says so.
• Close other tabs, which gives the converter more room.

If the page has photos, JPG is the smaller choice; for text pages, PDF to PNG gives cleaner edges.

The honest part: sometimes a screenshot is faster

For 1 page that you only want to show someone, your phone already has a converter: open the PDF, zoom to the part that matters, and take a screenshot. It is quicker than any website. The catch is that a screenshot has the phone screen’s size and shape (an iPhone 15 screenshot is 1179 x 2556 pixels) and includes whatever is around the page, so it is fine for a quick look and poor for anything that gets printed or posted.

Use the converter when you want whole pages at a set resolution, several pages at once, or a file that someone else will use. For posting pages to Instagram or WhatsApp, the Instagram guide shows the crop and size that fit; for choosing pages out of a long file, see converting specific pages. And for other jobs on the same phone, the guide to editing a PDF on a phone and compressing a PDF on an iPhone use the same browser approach.
