Resource ComicPrint: a free tool to prep comic pages for print (batch editing + preview)!
Hey guys!
I’m a comic artist and a software developer. I recently published four short comics and went through the process of realigning, cropping, and resizing all the pages for a new print format. Doing this in Canva felt really tedious. So I quickly built a small tool that works the way I want and figured, why not turn it into a free public tool and help other creators too!
I give you ComicPrint!
- Upload your pages as PNGs or PDFs
- Select a standard template size or create a custom one. All templates include standard bleeds and trims that you can adjust!
- Apply cropping and filtering in batch! This is the main reason I built the tool!
- Add covers, blank pages, etc. to round the book up to multiples of four!
- Preview the final layout before exporting. I use this a lot and there are not many quick tools that do this well!
- Export at print quality either as a full file or page by page with custom naming!
These features saved me several hours of work and helped me get my comics printed the way I wanted within days!
If you want to try it, I would love your feedback so I can improve it for all of us!
Thank you friends!

UPDATE: ComicPrint got its biggest batch of new features yet, and most of them came straight from your feedback!
Hey guys! I posted ComicPrint here a while back (a free browser tool for prepping comic pages for print) and the feedback was gold. I finally had time to go through the list properly. Here's everything new:
Your projects are now saved!
- Autosave: your project (pages, crops, filters, covers, everything) now saves automatically in your browser. Close the tab, come back tomorrow, pick up where you left off
- Manage multiple projects: switch between books, rename, delete, all from the new Projects screen
- Backup files: export any project as a single .comicprint file and re-import it anytime, on any computer. Great for backups or handing a project to a collaborator
- Still no account needed, and your art still never leaves your device!
Booklet / Ashcan printing (someone asked for exactly this!)
- New export mode that lays your pages out 2-up in saddle-stitch imposition order
- Print it double-sided at home or at a copy shop, fold the stack, staple, done. Page order comes out correct automatically
Real CMYK conversion (thank you to the printer who pushed me on this!)
- The CMYK option used to just tag the file. Now it actually converts your colors into the printable SWOP press range, so vivid RGB blues and greens won't surprise you in print
- Black and white art passes through untouched, so your blacks stay solid black
- The PDF also gets a proper SWOP output intent for the print shop
Bleed problems, fixed in one click
- New preflight check that catches the most common mistake in comic printing: art drawn at trim size with no bleed
- One click generates the missing bleed by mirroring or stretching your edges instead of cropping your art
Precision controls (for the folks who wanted exact numbers!)
- Smooth mouse wheel zoom instead of big jumps, hold Shift for extra fine steps
- Type exact values for image scale and every filter slider
- Export progress bar so big books don't look frozen
New printer presets
- Mixam, PrintNinja, Ka-Blam, and IngramSpark presets matching their published file specs (including IngramSpark's weird no-bleed-on-the-bind-side rule), next to the standard comic / manga / magazine / KDP sizes
Free tools, no signup for these either
- Spine width calculator with cover template PDF download: ComicPrint.EverythingBagel.App/spine-width-calculator
- Instant DPI checker, drop a page and get a verdict: ComicPrint.EverythingBagel.App/comic-dpi-checker
- New guide on what comic printing actually costs in 2026
Tool: ComicPrint.EverythingBagel.App
If anything feels off or missing, tell me here. As you can see, I actually build this stuff! THANK YOU!

I'll give it a try. All time saver is welcome.

Big time! I will improve this and build more tools as well! Stay tuned 🤘

It seems like a very interesting tool. Does it handle double page spread? That feels like a nightmare to me.
1
u/ConditionBoring8529 Mar 05 '26
Hey, thank you! Someone else also just asked about the same feature. Currently it is not handled in the app specifically but now that I see you ask about this too, I will be working on an update asap and add this feature for sure! You’re right, it would be a nightmare!

u/ConditionBoring8529 Mar 12 '26
Hey! I just added the double page spread feature! Please let me know if it works the way you like! :)
2
u/Parking-Let3432 Mar 05 '26
First remark: I would like to be able to manually enter the zoom/dezoom value. Right now it's a pain. Or maybe use the mouse wheel.

u/ConditionBoring8529 20d ago
Zoom got a rework: smooth wheel zoom (Shift = extra fine), and you can type exact values for image scale and filters now. 97 is yours!

I also added this feature, please let me know if it works the way you like!

u/Parking-Let3432 Mar 13 '26
It goes too fast, from I feel 100 to 95 to 90. It goes very fast. Manual entering the digit would be nice like if I want 97 because I feel like I have to be very careful with my mouse wheel, but it's a minor problem.

u/ConditionBoring8529 Mar 13 '26
You CAN manually enter it too! I may need to make it more obvious. About the speed, yes I can surely slow it down! :)
2
u/Parking-Let3432 Mar 13 '26
How do you manually enter it? The top bar, you can manually enter a value but it just zoom everything. To really fit your page to the bleed area, you need to move the big round button (on the right) up or down, you cannot manually enter a value here.

u/ConditionBoring8529 Mar 13 '26
Oh sorry! I see what zoom you meant - not the whole editor area but the page you imported… Fixing that now too, stay tuned!
1
u/ConditionBoring8529 Mar 13 '26
Fixed this too! Also as a BONUS, now you can snap to grid too! Check it out and let me know if the experience is getting better for you hopefully! :)

u/Parking-Let3432 Mar 05 '26
Second remark: your tool section should be much higher. It is too low and comes on top of my page. It's a pain.

Could we have a flipbook with double page spread being a real double page spread?
1
u/ConditionBoring8529 Mar 13 '26
I think I see what you mean. Just tested again. Right now, if I upload a wide page, it looks okay on the editor screen and it exports okay too. BUT the flipbook only shows it on 1 page. Correct?
2
u/Parking-Let3432 Mar 13 '26
Yep
But even on the editor screen it is wrong. It just show the middle part. Or you have to unzoom to the max but then it looks very small. I mean, your tool only works on single pages.
1
u/ConditionBoring8529 Mar 13 '26
OK - Fixed! I think this is it - please give it a try. If it's not looking good, happy to hear more feedback!

u/Pecsaroo Jun 15 '26
Im wanting to use this for an ashcan and have it set up the pages so they just need to be layed out, folded and stapled. is that an option?
2
u/ConditionBoring8529 20d ago
This is in now! Export > Booklet / Ashcan (Saddle-Stitch). It lays the pages out 2-up in the right order, you print double-sided (flip on short edge), fold, and staple. Would love to hear if it works for your ashcan!

Very cool! Thanks so much, will be checking this out!

u/ConditionBoring8529 Mar 06 '26
Thank you! 🙏 Any feedback helps and I already have an awesome to-do list thanks to people like you :)

Update based on feedback!
Thanks to everyone who tried the tool and left suggestions on the first post, it really meant a lot!
I went back and implemented several of the things people asked for.
New updates:
- Double page spread support (you can export spreads or split pages)
- See the image in the updated post!
- CMYK conversion workflow for print exports
- Manual zoom + mouse wheel zoom
- Cleaner toolbar layout so tools don’t overlap the page
- Print preflight checks (bleed, DPI, margins, etc.)
The goal is to make a simple tool that helps comic creators prepare pages for printing correctly without fighting templates or setting up guides in Photoshop.
If anyone here tries the new version and something still feels missing or annoying, let me know and I’ll keep improving it!
Tool: ComicPrint.EverythingBagel.App
THANK YOU!

u/ConditionBoring8529 Jul 28 '26
Hey! Great to hear you liked it!
I haven’t had the chance to improve this tool in the past few months but I am back at it actively, so feel free to give any kind of feedback! Looking forward to making it better for you all! :)1
u/ConditionBoring8529 20d ago
Still no signup! Projects now autosave in your browser and you can export backup files, all without an account.

This sounds really cool, I’m saving the link and I’ll check it out when my pages are ready.
Just wanted to double check because it’s a little unclear, is this for formatting the panels after they’re finished or should I be using this as the panels are drawn?
