Ebook Cover Vectorization Needed

I have six AI-generated front covers and one matching back cover for a Kindle ebook series. Here is the Google Drive link to the AI Generated images https://drive.google.com/drive/folders/1752K9m4YwL_udEwFuU0_4kHB8a6CA29z?usp=sharing They are currently in PNG format, and I need them rebuilt as fully editable vectors so I can scale and tweak them without quality loss. Once the artwork is vectorised, please export high-resolution TIFF or JPEG versions for upload to KDP. While redrawing, I’d like you to: • Resize dimensions to Kindle specifications • Adjust colours so they remain vibrant in both RGB and CMYK • Fix small AI imperfections (odd edges, artefacts, misaligned text and remove the fine line swirl found in all the images Please keep layer structures logical so I can edit titles, subtitles and author name later in Illustrator or Affinity Designer. If you rely on fonts that aren’t system defaults, include the font files or outline the text. Deliverables: layered vector files (.AI, .SVG or .EPS—whichever you prefer) for each cover, plus the final flattened TIFF/JPEG exports. I need a skilled designer to rebuild these as fully editable vector files and deliver Kindle-compliant cover exports. I also need one matching back cover that works for all six books. Deliverables 6 front covers, each as an editable vector master (.AI, .EPS, .SVG or layered PDF) with live, editable text and organized layers. 1 universal back cover in the same style, in an editable vector master. Kindle-ready exports of all 7 files (specs below). Social media versions of each front cover (specs below). A short README or note listing the fonts used (or outlined versions), color values (RGB hex) and layer structure. Creative Approach The source images are AI-generated raster artwork, so I'm open to your recommendation on the cleanest workflow. My suggested approach is a hybrid: Vectorize the flat, graphic elements: title blocks, banners, gold frames, checkmark bullets, scales-of-justice icon, badges, author bar, and simple shapes. Rebuild all text as live type using matching or close fonts, so titles and subtitles can be edited for future books. Rebuild it as clean vector paths, or retouch it in Photoshop and place it as a consistent layer, so it matches across the series. Keep complex illustrated scenes (characters, robot, money, courthouse) as high-resolution embedded raster layers, or redraw them as vector if you can do so faithfully. Please explain which you recommend and why. Deliver everything on separate, named layers so I can swap titles, subtitles and background art. Please describe your proposed workflow in your proposal. Kindle Cover Specifications (required for all front covers) Spec Requirement Format TIFF (.tif/.tiff) or JPEG (.jpeg/.jpg) Ideal dimensions 2,560 px height × 1,600 px width. For best quality on HD devices, at least 2,500 px height. Minimum dimensions 1,000 px height × 625 px width Maximum dimensions Must not exceed 10,000 px in height or width Aspect ratio Height/width of at least 1.6:1 (1,000 px wide = 1,600 px tall) DPI 72 dpi file setting, with a minimum resolution of 300 PPI for best quality File size Under 50 MB Color profile RGB (red, green, blue) Compression Minimal. Amazon applies extra compression on its website, so export at the highest quality. Color separation Save WITHOUT color separation. This is a pre-press or color palette option. Please verify it in your editing program or an image analysis tool. Borders Covers with white or very light backgrounds can disappear against Amazon's white page. Add a thin border or a darker edge if needed. Social Media Export Sizes (for each front cover) Please also include export promotional versions with these size dimensions: 1080 × 1350 px: Instagram, Facebook, LinkedIn, Threads and Reddit 1600 × 900 px: X (Twitter) 1080 × 1080 px: the safest all-platform square. Not ideal on any one platform, but it works everywhere. For every social size: Keep carousel slides the same ratio. Keep key content in the center 80%. Save as JPG or PNG in sRGB, under 5 MB.
