Pinterest rewards vertical, high-resolution imagery that reads clearly on phones and desktops alike. SynthQuery’s Resize for Pinterest is a free, client-side utility that exports pins to the widths and heights creators actually use: the 1000×1500 “standard” 2:3 frame that tends to dominate performance reporting, the taller 1000×2100 infographic-friendly long pin, a 1000×1000 square when you want balanced grid weighting, full-bleed 1080×1920 canvases for Story Pins and Idea Pins, the 165×165 square master for profile avatars (Pinterest displays them as circles in-product), the 222×150 board cover banner, and the same 2:3 card geometry called out for carousel slides and shopping pins. Nothing leaves your browser tab for resizing: files decode with standard web APIs, draw to a canvas, and download again—ideal for bloggers monetizing recipes, e-commerce brands syndicating catalogs, DIY creators publishing multi-step visuals, and agencies batching seasonal campaigns. The interface mirrors how social teams argue about crops: “fit” letterboxes with a color you control so no detail is lost; “fill” applies a Pinterest-tall or wide frame with a smart focal point you can steer with sliders or a click on the original preview; “stretch” maps every pixel when distortion is acceptable (rare for photography, occasional for flat graphics). Compare the original and the export side-by-side, flip to a compact tabbed view on small screens, and glance at a feed-style preview scaled to an approximate column width so you can judge legibility before upload. Batch a dozen assets and ZIP them in one click when you are prepping a content calendar. Export keeps the closest practical “original” raster type—JPEG stays JPEG, WebP stays WebP, PNG stays PNG—while formats that cannot round-trip through canvas the same way (notably animated GIF) fall back to a still PNG so you are never surprised by a silent format change without explanation. SynthQuery does not operate a Pinterest scheduler; this page is geometry and honesty for pixels. When copy around your pins needs verification, pair exports with the AI Content Detector or Humanizer from the main tools catalog; when you need alt text discipline, open the Alt Text Generator.

**Preset accuracy.** Each pin type lists exact output pixels beside its name in the selector so you never guess whether “long pin” means 2000 or 2100 px of height. Standard, carousel, and shopping presets share the 1000×1500 frame because Pinterest’s own guidance clusters those experiences around the same 2:3 visual grammar even though copy and commerce metadata differ in the uploader. **Crop semantics.** “Fit” is a contain operation: the entire source image stays visible inside the target rectangle, and SynthQuery fills the unused bands with your letterbox color—match hex 0c0c0f to SynthQuery’s dark chrome or sample a brand hex so the transition disappears against your mockups. “Fill” is cover-style cropping: the output stays sharp edge-to-edge, and the focal point biases which region survives when the source aspect ratio disagrees with Pinterest’s tall frames—critical for faces, hero products, and recipe hero shots. “Stretch” maps axes independently; use it sparingly, mostly for already-flat vector-like art where distortion is invisible. **Smart focal control.** Sliders expose normalized horizontal and vertical emphasis readable by screen readers; mouse and touch users can also click the original preview to drop the focal anchor where the subject already sits. The math mirrors CSS background-position intuition: you are nudging which part of the oversized draw rectangle remains inside the pin window. **Preview modes.** Side-by-side mode keeps creative review fast on laptops; stacked tabs reduce horizontal scrolling on phones. The feed preview uses a fixed approximate column width (236 CSS pixels) so you can sanity-check title-safe zones and text size before you commit to Scheduler uploads. **Batch & ZIP.** Every queued file inherits the same preset and crop mode for predictable folders; filenames append a “-pinterest-” preset tag before the extension so DAM imports sort cleanly. ZIP packaging uses the same JSZip dependency as other SynthQuery converters—archives are assembled locally. **Performance posture.** The hero tool loads through a dynamic import so the first paint stays light; previews debounce slightly to avoid recomputing canvas blobs on every slider tick. Quality sliders appear only when the selected source is JPEG or WebP because PNG exports are lossless from the canvas perspective.

Pinterest’s public guidance has evolved, but practitioners still converge on a few durable ideas: vertical pins outperform extremely wide crops in many discovery surfaces because phones dominate sessions; 1000 px on the short edge of a 2:3 pin is a widely cited sweet spot for clarity before compression; Idea Pins and vertical video-adjacent units often target 1080×1920 to align with phone-native capture. Pinterest may downsample or transcode after upload, so exporting slightly above minimum quality preserves edges after their CDN optimizes bytes. Aspect ratio interacts with how the grid masks thumbnails: when your source is too wide relative to the slot, the platform crops—often toward the vertical center—whether you planned for it or not. Pre-cropping in SynthQuery makes that decision yours. JPEG and WebP exports bake sRGB-ish values typical of canvas; embedded ICC profiles and EXIF from the camera do not survive export, which is usually desirable before social distribution but means you should archive RAW or TIFF masters elsewhere. Animated GIFs decode to a still for this pipeline; use dedicated GIF tooling if motion must remain. Why 2:3 keeps winning: it occupies more vertical scroll estate than 1:1 in multi-column layouts without reaching the extreme height where load times and cropping risk rise for casual photography. Longer pins can increase dwell when the content is genuinely tall (checklists, micro-infographics), but every extra hundred pixels costs attention—test saves and clicks rather than assuming height alone drives distribution.

**Blog and editorial promotion.** Publishers export 1000×1500 masters from horizontal hero photos by biasing the focal point toward the headline-adjacent subject, then reuse the same source for a 1000×2100 long pin that stacks pull quotes or chapter bullets. Because processing is local, embargoed shoots never touch a third-party image API. **E-commerce and catalog syndication.** Merchants normalize vendor JPEGs that arrive at random megapixel counts into shopping-ready 2:3 cards, keeping product chrome aligned in the grid. When SKUs share a template, batch ZIP hands social coordinators a single attachment per drop. **Recipe and food creators.** Tall pins reward step collages; long pin mode gives vertical room without scaling text to illegible sizes. Fit mode protects plated shots when the source DSLR frame is wider than tall—letterbox with a sampled background color pulled from the dish. **DIY, maker, and home content.** Workshop photos often mix landscape before/after pairs with portrait detail shots; fill mode plus focal clicks keep hands and tools inside the crop window while the feed preview confirms whether callouts remain readable. **Infographics and education.** Designers paste PNG slides from Figma exports, stretch only when art boards already match the pin aspect, and use square mode when repurposing the same asset to boards that favor 1:1 thumbnails. **Profile and board branding.** Profile and board presets are smaller targets; start from oversized masters so downscaling stays sharp, then upload the precise squares and banners the UI expects. Whenever accompanying blog posts might include AI-assisted copy, run SynthQuery’s detector stack from /tools before scheduling; the resizer itself never inspects text.

Start from the largest clean master you own—RAW, TIFF, or high-bit PNG from design tools—because Pinterest and SynthQuery cannot invent real detail when upscaling low-resolution scrapes. Drag images onto the drop zone, browse, or paste from the clipboard when screenshots arrive from Slack; the queue shows each file’s intrinsic width and height so you catch accidental thumbnails early. Choose the preset that matches the surface: standard 1000×1500 for everyday pins, long pin when text blocks or steps need height, square when art direction demands parity with 1:1 boards, story or idea presets for 1080×1920 vertical canvases, profile for the 165×165 avatar square, and board cover for the 222×150 banner. Carousel and shopping presets reuse the standard geometry—export one card per slide when building multi-image posts in Pinterest. Pick a crop mode before judging previews. Use fit when no pixel may be cropped away; set the letterbox color to your page background or a brand neutral. Use fill when the frame must feel immersive; drag focal sliders or click the original preview to keep faces, logos, or hero products inside the safe zone. Stretch only when you understand the distortion trade-off—common for abstract textures, rare for product photography. Toggle side-by-side preview for desktop review or switch to tabs on smaller breakpoints. Watch the feed preview column to ensure text overlays and faces survive at approximately real column scale. Adjust JPEG/WebP quality if file size matters for email handoffs—PNG ignores that slider. Download a single asset to validate in Pinterest’s own uploader, then use Download all as ZIP when the queue is ready. If animated GIFs are in the mix, remember only the first frame exports; plan GIF work elsewhere. When copy or disclosures accompany the campaign, run the AI Detector and Humanizer as policy requires, then return to the Free tools hub or https://synthquery.com/tools for the rest of the SynthQuery stack.

Canvas exports do not preserve EXIF metadata, animated GIF timing, or non-sRGB ICC profiles—archive originals when legal or color proofing requires them. Extremely large sources may hit browser memory ceilings; downscale in desktop software first if previews fail. Stretch mode can harm trust when product proportions change—reserve it for abstract art. Accessibility for the pin itself still depends on alt text, contrast, and legible typography; use SynthQuery’s Alt Text Generator and readability tools rather than relying on imagery alone. Pinterest’s algorithms and ad policies change; treat dimensions here as engineering-friendly defaults aligned to common practitioner references, not a substitute for Pinterest’s official help center when your account is in a regulated vertical.
