Cycling through all six. Tap any point to stop.

Measured on six things

Turn a photo into a cross stitch pattern with DMC threads

Growth

Real niche (photo-to-chart stitchers, Pattern Keeper users) with a concrete wedge: three colour versions side by side, DMC-matched, free and on-device. Category is crowded but the free-plus-tiny-upsell positioning is defensible.

About this app

Cross Stitch Pattern Maker turns a photo into a cross stitch chart in your browser. Upload a picture and it shows three versions with different numbers of colours side by side, each matched to real DMC thread numbers, and highlights the smallest one that stays close to your photo. Stray single stitches are cleaned up for you, and you can edit the chart, paint, fill, add backstitch or mark areas not to stitch. You get a printable PDF with a cover, a colour key and chart pages, a PDF for the Pattern Keeper app, an OXS file and a list of how many skeins of each thread to buy. Your photo is converted on your device and never uploaded; there is no account and no watermark, and patterns are saved in your browser. All of that is free. A one-time Project Pass (US$4.90 for 30 days) adds automatic background removal and many photos at once; Pro (US$7.90 a month or US$49 a year) adds cloud sync across devices. Card prices include tax, and PayPal is accepted.

Scout Review

Written by AI from measured evidence, scored out of 100.

CrossStitchPatternMaker.org is a focused, well-built indie tool that does one thing properly: turn a photo into a DMC-matched cross stitch chart in the browser, free, with no account and no watermark. The measured evidence backs it up — perfect Lighthouse scores, 11/12 security headers, 100/100 automated accessibility — and the hero design shows the actual output rather than stock imagery. The paid tiers are honest and small: $4.90 for 30 days of background removal and batch, $7.90/month for cloud sync. Weaknesses are real but minor: dense text-heavy lower sections, a text-only PDF table, no WCAG statement, no published audit. For a stitcher who wants their own photo as a chart without a subscription, this is a genuinely good option.

Measure by measure

Usability

Upload or try an example is the first thing you see, no account needed, and the free tier covers the whole core workflow. Long text-heavy sections and the 18+ checkbox add friction.

Design

Coherent green palette, disciplined display typography and a hero that shows real chart output next to the upload card. Dense grey paragraphs and padded step cards drag the lower half down.

Speed

Lighthouse 100/100 on both mobile and desktop: LCP 1.1s, CLS 0, TBT 1ms. Conversion happens on-device, so the heavy lifting never touches a server round-trip.

Security

HTTPS enforced with HSTS, CSP, frame protection, Referrer-Policy, SPF and DMARC — 11/12 header checks. Photos never leave the device and there's no account to breach. Permissions-Policy missing.

Accessibility

Lighthouse accessibility 100/100 on automated checks, responsive layout, clear button hierarchy. No published WCAG statement or multi-language support, so the score sits mid-band rather than top.

Growth

Improvement areas

Dense grey FAQ paragraphs and padded step cards make the lower page tiring to scan.
No WCAG conformance statement or multi-language support beyond automated a11y checks.
Missing Permissions-Policy header; no published audit or compliance certification.

Design & Usability

The homepage does the hardest design job well: the hero shows a real fox photo next to its pixelated chart with a DMC thread strip underneath, so you understand the output before you read a word. The green palette is consistent and the display typography is confident. Where it slips is below the fold — dense grey paragraphs, four step cards with big empty areas, and a text-only PDF table with no previews. Usability is strong where it matters: upload or try-an-example is the first action, no account is required, and the free tier covers the entire core workflow including the Pattern Keeper PDF. The 18+ checkbox adds a step and the long FAQ sections undercut the question-heading scannability they set up.

Speed & Security

Speed is the standout: Lighthouse 100/100 on mobile and desktop with LCP 1.1s, CLS 0 and TBT 1ms, and because conversion runs in the browser the heavy work never depends on a server response. Security is above category norms for an indie tool — HTTPS enforced with HSTS, CSP, frame protection, Referrer-Policy, SPF and DMARC, 11 of 12 header checks passing. The bigger security story is architectural: photos are converted on-device and never uploaded, and there is no account system to breach. The gaps are the missing Permissions-Policy header and the absence of any published audit or compliance certification, which is normal at this stage but keeps the score out of the top band.

Accessibility & Growth

Accessibility scores 100/100 on Lighthouse's automated axe-core checks, and the site is responsive with a clear primary/secondary button hierarchy. What's missing is anything beyond automation: no WCAG conformance statement, no multi-language support, and the long FAQ paragraphs are exactly the kind of content automated tools don't flag. Growth is a judgement on the idea: the target customer is specific (cross stitchers converting photos, Pattern Keeper users, pet owners, gift makers), and the wedge is concrete — three colour versions side by side, DMC-matched via CIEDE2000, free with no watermark, on-device. The category has incumbents (Stitch Fiddle, PCStitch) but the free-plus-tiny-upsell positioning and the Pattern Keeper export are real differentiators. The domain is brand new, which is context, not a score.

Conclusion

If you're a cross stitcher who has ever uploaded a pet photo to a chart maker and gotten back a muddy 40-colour mess, the three-versions-side-by-side approach with a highlighted 'fewest colours that still looks right' pick is the feature that will actually save you money on thread. The free tier is not a teaser — it produces the printable PDF, the Pattern Keeper PDF, the OXS file and the skein list. Pay only if you need background removal or multi-device sync. The main thing to watch is that patterns live in your browser: download the project file for anything you care about.

Suggestions for improvement

Add a WCAG 2.1 AA conformance statement and audit the long FAQ paragraphs for readability, not just automated checks.
Add the Permissions-Policy header to close the last gap in the 11/12 security header checklist.
Replace the text-only PDF download table with small preview thumbnails of the cover, colour key and chart pages.
Break the dense FAQ paragraphs into shorter answers with sub-headings or bullet lists to match the question-heading scannability.
