The right export depends on where the comic is going. A page for Instagram, a handout for class and a file for a print shop each want a different format and resolution, and choosing wrong gives you blurry prints or huge files. This guide explains the four image formats BlankComic exports, PNG, JPG, PDF and SVG, plus the .blank project file, and tells you exactly which to pick.
Quick Summary
- PNG for best quality, JPG for small files, PDF for printing several pages, SVG for vector editing.
- Quality presets: Web 72 DPI, Social 150 DPI, Print 300 DPI.
- Several pages as PNG or JPG download as one ZIP; PDF puts all pages in one file.
- Always keep a .blank project file: it is the only file you can reopen and edit.
The export formats at a glance
| Format | Type | Pages | Best for |
|---|---|---|---|
| PNG | Raster, lossless | One per page (ZIP for several) | Best quality: social media, websites, home and shop printing |
| JPG | Raster, compressed | One per page (ZIP for several) | Smaller files for email, messaging and slow connections |
| Document | All pages in one file | Printing, handouts, zines and submissions | |
| SVG | Vector | Current page only | Embedding on websites, editing in Inkscape or Illustrator |
| .blank | Project file | Whole project | Reopening and editing later in BlankComic |
Open Download in the editor, or press Ctrl + E (⌘ + E on a Mac), to see all five options.
PNG: the everyday choice
PNG stores every pixel exactly, with no compression artefacts, which keeps line art and lettering crisp. It is the safest default for sharing online and for printing at home or at a shop. The trade-off is file size: a full-colour page at 300 DPI can be several megabytes.
JPG: smaller files
JPG compresses the image to make the file much smaller. BlankComic’s compression slider starts at 85%, a good balance; lower it for tiny files, raise it for quality. JPG can blur thin lines and flat colour slightly, so prefer PNG for anything you will print or zoom into.
PDF: for printing and handouts
PDF exports every page into a single file in the right order. That is what you want for a worksheet set, a zine, a comic you will print at a shop or a file you hand in. It opens on any computer or phone without extra software.
SVG: vector for the web and editing
SVG describes the page as shapes rather than pixels, so it stays sharp at any size. Use it to place a page on a website or to keep editing panel borders and bubbles in a vector program such as Inkscape or Illustrator. SVG exports the current page only, and most print shops prefer PDF or high-resolution PNG.
Which DPI should you choose?
For PNG and JPG, BlankComic offers three quality presets. DPI is dots per inch: the higher it is, the more pixels each inch of the page gets.
| Preset | DPI | Use it for | A4 page in pixels |
|---|---|---|---|
| Web | 72 | Quick previews, small web images | ≈ 595 × 842 |
| Social | 150 | Instagram, Facebook, messaging, school slides | ≈ 1240 × 1754 |
| 300 | Home printing, print shops, anything on paper | ≈ 2480 × 3508 |
Tip: The formula is inches × DPI = pixels. A US comic page at its 6.625 × 10.25 in trim is about 1988 × 3075 px at 300 DPI. Every common size is in the comic book page size chart.
Which format for which job?
| You want to… | Format | Quality |
|---|---|---|
| Post on Instagram or Facebook | PNG (or JPG if the file is too big) | Social, 150 DPI |
| Send by email or WhatsApp | JPG | Social, 150 DPI |
| Put a page on a website | SVG, or PNG | Web or Social |
| Print at home | PDF, or PNG | Print, 300 DPI |
| Send to a print shop or print-on-demand | Print, 300 DPI | |
| Upload to WEBTOON Canvas | PNG or JPG, then resize to 800 px wide | Print, then resize |
| Keep editing later | .blank | — |
Webtoon uploads have their own limits on width and file size; see webtoon canvas size in pixels. For KDP paperbacks, see the KDP blank comic book interior guide.
Exporting several pages
- PDF always includes all pages, in order.
- PNG and JPG can export just the current page, or every page packed into a single ZIP file.
- SVG exports the current page.
Always save a .blank project file
PNG, JPG, PDF and SVG are finished pictures: you cannot reopen them in BlankComic and carry on editing. The .blank project file keeps every panel, bubble and page editable. Save one with Ctrl + S (or from Download) before you close the tab.
Check this: BlankComic autosaves your work in the browser on your device and never uploads it. That is private, but clearing browser data or switching computers loses the autosave. The .blank file is your backup.
Printing tips
- Use 300 DPI for anything on paper.
- Print at 100% scale (“Actual size”) so the page is not shrunk to fit printer margins, unless you want it to be.
- Colour: exports are in RGB, the standard for screens and almost all home and print-on-demand printing. If a commercial printer asks for CMYK, convert the file in an image editor and check the colours.
- Bleed: art that touches the page edge needs bleed; the editor shows a 3 mm bleed line and a safe zone to help. Details in the page size guide.
Frequently Asked Questions
What is the best format to print a comic?
PDF at the Print (300 DPI) setting for multi-page comics and print shops, or PNG at 300 DPI for single pages.
Should I export my comic as PNG or JPG?
PNG for the best quality and crisp lines; JPG when you need a much smaller file, for example for email or messaging.
What DPI should a comic be for print?
300 DPI. In BlankComic choose the Print quality preset. Use 150 DPI (Social) for screens and social media.
Can I export all pages at once?
Yes. PDF puts every page into one file, and PNG or JPG can export every page as a ZIP archive.
What is a .blank file?
BlankComic’s project file. It keeps your comic editable, so you can reopen it later or on another computer. Images and PDFs cannot be edited again in BlankComic.
Does BlankComic export in CMYK?
No, exports are RGB. Most home printers and print-on-demand services accept RGB; if a printer requires CMYK, convert the file in an image editor.
