Key details about this service to help you decide. Generated by Zinn Hub, not the seller.

Source File Requirement

PSD or AI Required (Base)
The basic package requires you to provide an editable PSD or AI source file. However, the seller also indicates they can work with JPG, PDF, or PNG files — contact them first to confirm your file type is supported before ordering.

Platform Coverage

KDP, IngramSpark, Kindle & Print-Ready
Covers are tailored for major publishing platforms including Amazon KDP, IngramSpark, Kindle, and print-ready formats. Technical issues like bleed errors and formatting rejections are also resolved as part of the service.

Revision Allowance

3 (Basic) → Unlimited (Premium)
The base package includes 3 revisions with 3-day delivery. Upgrading to Premium unlocks unlimited revisions, source file delivery, 3D mockup, and back & spine design — all at 2-day turnaround.

Rejection Fix Guarantee

Re-submission Until Accepted
If your cover upload is rejected by a publishing platform, Zinn Digital guarantees to fix and resubmit at no extra charge. Note that nominal fees apply if design modifications (beyond technical fixes) are requested alongside the correction.

What You'll Receive

Formats:
Digital FilesSource Files
Delivery Method: Order Manager
Notes: Your completed, print-ready cover file will be delivered via the order manager. Standard delivery is a high-resolution PDF, JPG or PNG formatted to your platform's exact specifications. Source files (PSD or AI) are included where selected. Please check your files against the platform template before uploading, and raise any concerns via the order chat — we will resolve them promptly.

Full Description

Your book deserves a cover that passes every technical check — first time, every time. Whether your file has been rejected by Amazon KDP, flagged for bleed errors, or simply needs resizing for a new format, Zinn Digital's London-based team of professional graphic designers and experienced KDP publishers will resolve the issue swiftly and deliver a fully print-ready result.

We specialise exclusively in book cover design and formatting: front covers, full wraparound paperback covers (front, spine and back), Kindle and eBook covers, IngramSpark covers, and audiobook covers for ACX. Because we are KDP publishers ourselves, we understand the exact specifications, margin requirements and colour profiles demanded by each platform — and we resolve every issue until your file is accepted, at no extra charge for technical corrections.

Working without an editable source file? No problem. Even if all you have is a JPG, PNG or PDF, our team can reconstruct, upscale and reformat your cover to meet the required specifications. If you do have a PSD or AI source file, the process is even faster and the output even sharper.

What we handle:
— Bleed errors and incorrect canvas sizing
— Spine width adjustments for updated page counts
— Resolution and colour-profile corrections (CMYK, RGB, sRGB)
— Platform rejection fixes for KDP, IngramSpark and Kindle
— Front cover modifications: fonts, colours, images, layout
— Full wraparound cover builds including spine and back matter
— 3D mockup renders for marketing and promotional use
— Source file handover (PSD or AI) for future self-editing

How it works: place your order, send your existing files and a brief summary of what needs changing via the order chat, and we get to work. If we need any clarification, we will reach out immediately so there are no delays. Revisions are included in every tier — unlimited on our top package.

This service is ideal for self-publishing authors, small presses, hybrid publishers, and anyone whose cover has been rejected or needs updating for a new edition, trim size or distribution channel. Whether you need a quick technical fix or a full wraparound redesign with a 3D mockup, Zinn Digital has the right package for you.

Frequently Asked Questions

Yes. We resolve all common rejection reasons including incorrect bleed, wrong canvas dimensions, low resolution, incorrect colour profile, and spine-width errors. We will keep correcting the file until your upload is accepted, at no additional charge for technical fixes.

Absolutely. Even without a PSD or AI file, we can reconstruct, upscale and reformat your cover from a JPG, PNG or PDF. The Essential Fix tier is perfect for this. If you do have a source file, results will be even sharper.

The Essential Fix tier delivers within 3 days. The Standard Package delivers within 2 days. The Full Wraparound delivers within 4 days given the additional surfaces involved. If you need the work completed within 2 hours, please add the Rush Delivery add-on before ordering.

Please send your existing cover file (PSD, AI, PDF, JPG or PNG), a clear description of the changes or fixes required, and your target platform (e.g. KDP paperback, Kindle, IngramSpark). If you have a print template or spine-width calculation, please include that too. You can share everything via the order chat once your order is placed.

The Essential Fix and Standard Package cover front-cover work. The Full Wraparound tier includes the complete three-surface cover: front, spine and back. If you need spine and back added to a lower tier, please get in touch via the order chat before purchasing so we can advise the right option.

We will optimise your image as much as technically possible. Where a source image is very small, we will advise you honestly via the order chat before proceeding, so you always know what to expect.

You will receive a high-resolution, print-ready file in the format required by your chosen platform (typically PDF for print, JPG or PNG for eBook). Source files (PSD or AI) are included in the Standard Package and Full Wraparound tier, or available as a standalone add-on.

Revisions are included in every tier: 3 with Essential Fix, 6 with the Standard Package, and unlimited with the Full Wraparound. Each revision request should be submitted via the order chat with clear, consolidated feedback. Unlimited revisions apply to the agreed scope of work.

I needed several book covers resized and tweaked before publication, and this Zinner was an absolute lifesaver! He did everything I asked in record time, and he was so proactive in his communication. I will definitely be hiring him again if I find myself needing book cover adjustments in the future!

I recommend this Zinner for graphic design help. He helped me resize my book cover image and remake it in different formats. I'm not sure where our communication got muddled about what was needed, but we got there in the end.

#1 recommendation. If you make it clear what you need done and do not make assumptions, he will be INCREDIBLE. His work was GREAT and VERY FAST. His response time was the best I've ever seen from anyone on Zinn Hub, from start to finish. His primary language is not English, so just speak clearly. Don't rush through the hiring process. This Zinner is a very hard worker and does things quickly, but just make sure he knows what ALL your expectations are and it will be a GREAT experience working with him.

I kept getting errors because of the sizing of the cover for Amazon KDP Publishing. I sent this Zinner my cover, and the next day it was delivered and passed with flying colours!
