All tools

Every tool here runs inside your browser. Your files are processed on your own device and are never uploaded to a server — which also means the tools keep working offline once the page has loaded.

• Product Photo Pipeline — All Four Steps in One Pass

  Remove a flat background, make it pure white, trim the wasted margin, drop the product into a marketplace frame at 85% and compress to a target file size — one canvas, one encode, one download. The only tool here that does the whole chain.

• Resize Product Photos

  Batch-resize photos to the exact pixel size a marketplace requires — Amazon, eBay, Etsy, Shopify, Shopee and more. Square white backgrounds, custom dimensions, all in one pass.

• Make Background White

  Remove a flat studio background from a product photo and replace it with pure white. Adjustable tolerance, edge cleanup, and an option that stops dark details inside the product from being punched out.

• Compress to a File Size

  Give it a limit — 100 KB, 2 MB — and it finds the best quality that still fits, shrinking dimensions only when quality alone cannot get there. Built for upload forms and attachment limits.

• Convert Image Format

  Batch-convert between WebP, PNG and JPEG. Asks you what to do about transparency instead of silently turning it black, and only offers formats your browser can genuinely encode.

• Convert HEIC to JPG

  Turn iPhone and iPad photos into JPGs that open everywhere. Brings its own HEIC decoder so Chrome and Edge can read them, keeps full resolution, handles a whole batch, and never uploads your photos.

• ID & Passport Photo

  Crop to a documented passport, visa or ID size at 300 dpi, replace the background colour, and lay copies out on a 4×6 print sheet. Includes framing guides for head height and eye line.

• Batch Rename Files

  Rename a whole folder with a pattern, numbering and find-and-replace. Renames the real files on disk through the browser's file system API — nothing is uploaded, nothing is copied.

• Split Image into Tiles or Strips

  Cut one image into a grid of equal square tiles for a grid post, or slice a long screenshot into strips with optional overlap. The crop snaps to a size that divides evenly so no tile is a pixel short.

• Listing Title Length Checker

  Compare one product title against the character limit of Amazon, eBay, Etsy, Walmart and Google Shopping at once, with a word-boundary truncation for each and a scan for phrasing that gets listings suppressed.

• Images to PDF

  Build one PDF from a stack of photos without re-compressing them. A JPEG is embedded byte for byte, so resolution and quality are exactly what you selected — most converters decode and re-encode, and that is where the detail goes.

• Merge PDF

  Combine several PDFs into one, in the order you set. Each file keeps its original page size, and a password-protected file is named and left out rather than silently producing a document with pages missing.

• Remove Photo Metadata (EXIF & GPS)

  See what a photo carries before you publish it — camera, editing history, timestamps, and the coordinates where it was taken — then download a copy with those blocks stripped. The compressed image is copied through untouched, so there is no re-encode and no quality loss.

More tools are on the way. This page grows as each one goes live.

Marketplace requirements

The pixel size, the background rule and the title character limit each marketplace asks for — Amazon, eBay, Etsy, Walmart, Google Shopping, Shopify, Shopee and Taobao — collected into one table, with a note of when each figure was last checked: marketplace image and title requirements.

Guides

Three reference pages sit alongside the tool guides, covering rules that apply across several tools at once: Etsy's documented image rules, what 300 dpi actually means, and processing a large batch without losing quality. The rest of this section is one guide per tool.

Every tool has a written guide underneath it. The guide goes further into one specific problem — the sizes a platform actually asks for, why a file gets rejected, which setting to change first. Start with whichever problem you have right now.

• Preparing product photos for online marketplaces — required pixel sizes, background rules, aspect ratios and the mistakes that get listings rejected.
• How to get a pure white background for product photos — why a background that only looks white still fails, and how to fix a backdrop without leaving a grey fringe.
• What to do when an image is too big to upload — why the limits exist, which of the three levers to pull first, and a size reference for common destinations.
• WebP vs JPG vs PNG: which format should you use? — what each format is good at, where WebP support still fails, and how to decide quickly.
• How to convert HEIC to JPG — why an iPhone photo will not open on Windows, the fix on each system, and the camera setting that stops it happening at all.
• How to write a product title that fits — the information order that survives truncation, and worked examples of titles that get cut or suppressed.
• File naming conventions that stay sorted — date formats that sort correctly, zero padding, and the characters that break things downstream.
• Planning a grid post, and slicing long images — how a grid post is assembled, why the posting order matters, and keeping detail off the seams.
• Why ID and passport photos get rejected — the framing, background, expression and resolution rules, and how to check yours before you submit it.

How to use these tools

Each tool page has the tool at the top and a short written guide underneath. The guide explains what the settings mean, which values are right for which platform, and the mistakes that most often cause a file to be rejected.
