Cross-posting product shots
Drop one master shot, generate Instagram square (1080 × 1080), OG image (1200 × 630), and X header (1500 × 500) in one batch. Each preset crops or letterboxes correctly so the subject stays visible.
Badilisha saizi za picha kwa vipimo halisi, asilimia, upande mrefu zaidi, au kiolezo cha mitandao ya kijamii. Shughulikia hadi picha 20 kwa wakati mmoja — kila kitu hufanyika kwenye kivinjari chako.

Zinazokubaliwa: JPG, PNG, WebP, GIF, BMP — hadi picha 20 kwa wakati mmoja
Kasi, faragha, kwenye kivinjari pekee — badilisha saizi za picha kadhaa na uzipakue kwa mbofyo mmoja.
Chagua vipimo halisi, asilimia, kikomo cha upande mrefu zaidi, au kiolezo cha mitandao ya kijamii.
Dondosha folda nzima. Picha moja hupakuliwa moja kwa moja; nyingi hufungashwa kwenye ZIP.
Kila kitu hufanyika kwenye kivinjari chako kupitia Canvas. Hakuna picha inayopakiwa kamwe — zima mtandao na bado kinafanya kazi.
Toa kama JPEG, PNG, WebP, au hifadhi muundo wa asili. Ubora wa JPEG / WebP unaweza kurekebishwa.
Mbofyo mmoja kwa Instagram square / portrait / story, OG image, X header, YouTube thumbnail, LinkedIn banner, na zaidi.
Funga uwiano unapoandika vipimo, au chagua kiolezo nasi tutaweka mistari ya pembeni kwa rangi ya mandharinyuma unayochagua.
Four resize modes, 16 social presets, all powered by browser-native canvas.
Pick exact dimensions (1080 × 1080), a percentage (50%), a longest-side cap (2048 px max edge), or a social-media preset (Instagram square, OG image, YouTube thumbnail, X header, etc.). Each mode handles edge cases differently — letterboxing, aspect-ratio locking, or stretch.
createImageBitmap decodes the source. OffscreenCanvas handles the resampling using bilinear filtering for downscale and bicubic for upscale (browser-implemented). High-quality smoothing is enabled by default to avoid the "crunchy" look of nearest-neighbour shrinking.
When the target aspect ratio doesn't match the source, you can either crop, stretch, or letterbox with a chosen background colour. Letterboxing is recommended for social media presets — fills with brand colour, keeps the original framing intact.
Choose the output format and quality (for lossy formats). Single image downloads directly; batches of multiple images bundle into a ZIP using the same pure-JS encoder as our image compressor.
One source image, multiple platforms, in 30 seconds.
Drop one master shot, generate Instagram square (1080 × 1080), OG image (1200 × 630), and X header (1500 × 500) in one batch. Each preset crops or letterboxes correctly so the subject stays visible.
Quickly resize a hero image to exactly 1200 × 630 — the size every social platform expects for link previews. Save as WebP for smaller file size with no visible quality loss.
Resize a square avatar to 400 × 400 (small) or 800 × 800 (large) — exactly the sizes Discord, Slack, and GitHub want. JPEG quality 90 keeps the file under 100 KB.
50 photos at original 12-megapixel resolution → 50 photos at 1920-px longest side, packaged as a single ZIP. The ZIP fits comfortably in any email provider's limit.
Resizing a personal photo to share online still involves uploading the unmodified original to most resize sites. iKit performs the resize in your browser using OffscreenCanvas, so the original bytes — full resolution, full EXIF — never leave your device. Only the resized output exists, and only on your machine.
Hapana. Kubadilisha saizi hufanyika kabisa kwenye kivinjari chako kupitia Canvas API. Picha zako hazitoki kwenye kifaa chako kamwe — unaweza kukata mtandao baada ya ukurasa kupakia na zana bado inafanya kazi.
Ingizo: JPG, PNG, WebP, GIF (fremu ya kwanza pekee) na BMP. Tokeo: JPG, PNG, WebP, au hifadhi muundo wa asili. Matokeo ya GIF na BMP hubadilishwa kuwa PNG.
Vipimo = upana × urefu halisi. Asilimia = punguza/ongeza kwa asilimia ya asili. Upande mrefu zaidi = weka kikomo cha upande mrefu (muafaka kwa vijipicha). Kiolezo = chagua saizi maarufu ya mitandao ya kijamii.
Hadi picha 20 kwa kundi, 30 MB kila moja. Picha moja hupakuliwa kama faili moja kwa moja; picha nyingi hufungashwa kwenye ZIP moja.
Vivinjari hutumia bilinear sampling. Kwa matokeo bora wakati wa kupunguza sana, ongeza ubora wa JPEG / WebP hadi 90+. Kuongeza saizi ya picha ndogo, hakuna programu (kivinjari au nyingineyo) inayoweza kurudisha undani usiokuwepo kwenye chanzo.
